Action Failed: Could not interpret MSTest results

I am running builds using FinalBuilder 7 (7.0.0.1065) on a Windows Server 2003 machine.

My builds are randomly failing on an MSTest action running tests on Visual Studio.NET 2010

I am getting intermittent, random build failures where all the MSTest unit tests pass, but the action fails with the following error message:

Hi Ted

Could you send us (to support at finalbuilder dot com )the TMKProTestProject.dll.trx file so we can test it under a debugger and see what is happening?
