Any idea on how I can fix this? I'm on windows 7, IIS 7, SQL 2008.

Thanks

Thanks for your suggestion, trying to run the resource got me to a telerik forum where they suggested that the issue could be caused by using the classic app pool. Switched to integrated and now I'm getting a different error (see below)

System.InvalidOperationException: '~/Telerik.Web.UI.WebResource.axd' is missing in web.config. RadStyleSheetManager requires a HttpHandler registration in web.config. Please, use the control Smart Tag to add the handler automatically, or see the help for more information: Controls > RadStyleSheetManager at Telerik.Web.UI.RadStyleSheetManager.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I've checked the web.config, and the entry for this handler is there. What gives?
