Resharpers testrunner simply ignores all my tests

I have a solution with a lot of nunit tests in different projects.
When I run resharpers testrunner, it finds all the tests. But when it comes to execution it simply marks them all as grey and silently completes.

How do I figure out whats wrong with the testrunner, and most importantly how do I get it to run my tests.
I have resharper 6 in visual studio 2008. My code is on a fileshare, and everything runs in a virtual machine.

Is there any way for me to turn on more logging or info from resharper, this silent treatment is starting to rub off on me.
