I have an accelerator plugin that I downloaded and set up to run with my existing CRM system. This is an ASP.net project and when I run it on my computer from my VS2005 environment, it runs fine. It also runs fine in IIS on my machine that my development environment is on. Both my machine and the server I am deploying to have IIS 7 and are running in integrated mode (not sure if that is an important detail or not).
When I deploy the project and move the deployed files to a webserver and try to view the site I get:
Server Error in '/' Application.

I have found one Microsoft KB saying this is caused by "circular references" but I can't seem to identify any. Also the alternative fix that is suggested is to use a <compilation> element in the web config with batch="true". I tried this and ASP.net says <compilation> is an unknown element. The KB I am refering to is here: http://support.microsoft.com/kb/919284 .

Am I missing something here?
