AJAX and the converted site

I've converted my existing site to 2.0 from 1.1 using the Visual Studio add-on that allows deployment of web projects. Once I converted it, I created a new page with a simple update panel containing a button and a label (the most simplistic of examples) and when clicking the button, I get an 'Unknown Error' alert. When I try to add an UpdatePanel to my existing page, I get

--------
Microsoft Internet Explorer
--------
Assertion Failed: can't find last / in base url

Break into debugger?
--------
OK Cancel
--------

When I create a new ATLAS project, everything seems to work fine. I did notice that if I change the home directory of the default site while the new ATLAS project is still open and then try to click the button in the update panel, I get an 'Unknown Error' popup as well. The reason this might be relevant is because my original 1.1 project was set up to look at the web root as it's location (localhost) as opposed to an application folder (localhost/project). I don't remember why I did this as it was about three years ago. Could this be an issue? How would I go about modifying project files to look at an application folder instead to see if this is the root issue?

Any help is greatly appreciated.

Nevermind. I was using the CTP (did I get that right?) and the beta 2 resolved my issues.
