"Build fails" when running NUnit tests

Hi,

I recently installed ReSharper 5.1 and built a very small test project (1 class, 1 test class). Unit testing is set to "Always Build".
When running my tests I get the message "Build fails". I found the following topic and followed the instructions (http://youtrack.jetbrains.net/issue/RSRP-157098). Every setting in my project seems to be fine.
What could be the issue?

Thanks a lot,
Aline
