Hi Chris,
I just install the Visual Studio 12 that comes with the Visual Cobol installation.
Yes I have both product in my machine: VC for Visual Studio 12 and VC for Eclipse. I installed the Eclipse version when the problem appeared with Visual Studio.
I tried to open WINBook sample. The solution explorer shows all the content but when I click to open BookException.cbl an exception error (attached) is shown.
ActivityLog.xml show this error:
