Could not Load file or assembly: Telerik.Web.UI, version 2007.3.1314.35

I started a webpage, used some prometheus tools (grid, tabs,...). Everything worked. I closed the program. Went away for a few days, came back, loged in, opened the program... and bang...
Without changing a thing VS2008 gives me this error om virtually every (but not all) tool I used (in design view).

The strange thing is that everything still compiles and the webpage still works.
But changing/adding thing sdoes not work at al

Any ideas?

How can I get him to find this file again? It is still showing in references and I still have all the tools available in the toolbox.

The problem is (let's hope) solved by putting the Telerik.Web.UI in the GAC but the question remains....why did it work first and then (without changing anything) not anymore?

Vista updates?
VS2008 did not have any updates by my knowledge.

Hello Daniel,

We must admit there was a similar problem with the previous RadControls Prometheus versions and adding the Telerik.Web.UI in the GAC resolved that. I'd suggest you uninstall that and download/install the latest Prometheus "Futures" build we uploaded a week ago. You would no longer get this problem.

Sincerely yours,
