In my current CI process the build will run fine and the dotcover tests will run without an incident but out of the blue my CI process will error out with the following:

[JetBrains dotCover] Coverage session finished [12/3/2012 1:59:32 PM]

[JetBrains dotCover] Coverage session finished but no snapshots were created.  E:\dotcover.msbuild(80,5): error MSB3073: The command ""E:\Program Files (x86)\JetBrains\dotCover\v2.0\Bin\dotCover.exe" a /TargetExecutable="C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\MSTest.exe" /TargetArguments="/testcontainer:"E:\Dev\bin\somefile.Tests.Unit.dll"" /Filters=+:"somemodule"  /TargetWorkingDir="E:\dotCover" /ReportType:HTML /Output="E:\CodeQuality\dotCover\somefile.htm" /LogFile="E:\dotCover\somefile.Tests.Unit.dotCover.Report.log"" exited with code -2.

Done Building Project "E:\dotcover.msbuild" (CheckOneAssemblyFile target(s)) -- FAILED. Done Building Project "E:\dotcover.msbuild" (dotcover target(s)) -- FAILED.  Build FAILED.

Anyone has experience this before?  I'm using DotCover version 2.0.425.54.  Any hints as to what could cause this error is greatly appreciated.
