Hi, I just started working with Unity, and I am having an error pop up every time I try to run the executables of my own games (the demos work fine). Here is the error:

OpenMutexA failed with error 2: The system cannot find the file specified.

I am also running the getReal3D plug-in, in case that makes a difference. Does anyone know how I can find out which file is missing?

Thanks in advance for any help.
