exception of type 'System.Exception' in JetBrains.ReSharper.UnitTestSuppor

In VS2005 with resharper my my Nunit tests do not work (anymore).

If I run the unit test in my project (it's a solution with 3 projects, one contains the unit tests) it shows "test has not run".

If I debug a test I get in the output console:
A first chance exception of type 'System.Exception' occurred in JetBrains.ReSharper.UnitTestSupport.NUnit.dll

Attached is the resharper logfile. All those "could not load assembly" errors with file not founds appear to be solved by a "better candidate name" log.

But the "Could not find project..." are weird.

Anyone knows of a solution? It had been working for a few days, but apparently I changes something in my solution/projects. I already reinstalled resharper. But that did not help.

Thanks a lot. Wessel
