Can't see downloaded image
If you download a Vesalius image without logging in first, the image will appear as a blank square. After you login, you'll be able to download images successfully by right-clicking on them and then saving them to your local hard drive.

Can't login with subscription token
You can't use your subscription token to login to Vesalius because a token is not a subscription – a token is a form of payment for a subscription. To login to Vesalius, you need to set up your account by completing the short subscription process.

The first step in this process is choosing your User ID, which can be any combination of at least six alphanumeric characters (e.g. "tjohnson35", "jennylee", "274427", "soxfan"...) that hasn't already been chosen by another Vesalius user.

After choosing your unique ID, you will be forwarded to the subscription page, where you will provide your demographic information and your e-mail address. At the bottom of the subscription page, you will be asked to pay for your subscription using either a token or a credit card.

When you click the "Use prepaid subscription token" radio button, and then enter your token in the form and click the "Submit Token" button, you will immediately be e-mailed a message containing your chosen User ID and a randomly-generated password. When you receive this message, the process is complete, and you can use your ID and password to login to Vesalius. (After logging in, you can change your password at any time, using the form at the bottom of the Vesalius home page.)

Redirection to the login form
When you click a link to one of your Vesalius Personal Pages and are instead redirected to the login form, it means your Vesalius session has terminated. There are two principal causes for terminated sessions:

1. Session timeout. If you have not requested a new Vesalius page for over 20 minutes, your session will time out. Before this happens, a "session-timeout warning" should appear in a pop-up window. The session-timeout warning notifies you that your session will expire out if you remain inactive for two more minutes, and provides a button you can click to extend your session for an additional 20 minutes.

If your sessions are timing out and you are not seeing the session-timeout warning, it may be because your browser is configured to block pop-up windows. To correct this problem, make sure that Vesalius is allowed to display pop-up windows.

If you use Internet Explorer, select the "Internet Options" item from the "Tools" menu. Then click the "Privacy" tab. If the "Block pop-ups" checkbox is checked at the bottom of the Privacy window, click the "Settings..." button. In the "Pop-Up Blocker Settings" window, enter * into the "Address of Web site to allow" field, then click the "Add" button. After * has been added to the "Allowed Sites" list, click the "Close" button.

2. Session-cookie blocking. Vesalius uses Microsoft's Active Server Pages (ASP) technology to build content pages from our database and to verify that users requesting content pages are validly logged-in. To keep track of logged-in users, ASP sets a "session cookie" on your PC at the time you login to Vesalius. This session cookie contains only one piece of data (the numerical ID of your session), and is deleted from your PC at the time your session expires.

If your browser is configured to block all cookies, ASP can't set a session cookie on your PC, and Vesalius can't identify you as a logged-in user. Since you don't appear to have logged in, Vesalius redirects you to the login form.

To correct this problem, make sure that Vesalius is allowed to set a session cookie on your PC. If you use Internet Explorer, select "Internet Options" from the "Tools" menu. Then click the "Privacy" tab. Make sure that your privacy settings are not set at the highest level of "Block All Cookies". (Alternatively, you can click the "Advanced" button in the Privacy window, then click both the "Override automatic cookie handling" checkbox and the "Always allow session cookies" checkbox.)

Anti-virus and privacy-protection programs are another possible source of session-cookie blocking. If you have the McAfee PrivacyService installed on your PC, open McAfee Security Center, then click the PrivacyService tab. Click the "Manage User Accounts" link. In the pop-up window, select the "Administrator" user name, then click the "Edit" button. Click the "Cookies" tab, then click the "Accept all cookies" radio button. To finish, click the "Apply" button, then click "OK" and close the PrivacyService window.

Can't view GIF animations
Many Vesalius narratives use simple GIF animations (generally 2-10 images that play in a repeating sequence for 1-3 seconds each) to illustrate medical conditions or surgical techniques. If you see only a static image where a narrative implies an animation should be, your browser may be set to block animations from playing in web pages.

To correct this problem, make sure that your browser is configured to play animations in web pages. If you use Internet Explorer, select "Internet Options" from the "Tools" menu. Then click the "Advanced" tab. Scroll down through the "Settings" list to the "Multimedia" category, then make sure that the "Play animations in web pages" checkbox is checked.

Can't view QuickTime videos
To view Vesalius videos, you need the QuickTime player installed in your browser. Try the link below to test whether you can view the QuickTime videos on Vesalius:

If you can't see these videos, try downloading and installing the free QuickTime player for your browser from the Apple website. To download QuickTime, click the link below, then follow the instructions provided by Apple.

If you still can't see these videos and you're using Internet Explorer for Windows, make sure IE is configured to allow the use of third-party ActiveX controls and multimedia plug-ins.

For IE 8: from the pull-down menu select "Internet Options" => "Security". Click the "Custom Level" button and scroll to the "ActiveX controls and plug-ins" section. Scroll down to the radio-button selection for "Display video and animation on a webpage that does not use external media player". Click the "Enable" button. Restart your browser.

Can't view Shockwave transparencies
To view Vesalius transparencies in the Shockwave format, you need the Shockwave player installed in your browser. To download the free Shockwave plug-in from the website Macromedia, click the link below, then follow the instructions provided by Macromedia.
