Unable to Activate Visual COBOL Personal Edition for Eclipse

Hi Guys.

I'm a student, and in college we're using Visual COBOL.

At home, I have both VS and Eclipse installed.

 

At first, I succesfully installed VC for VS, and it activated fine.

Later, I tried to activate the Eclipse version, but I'm not getting to.

 

I've already tried different emails, uninstall and reinstall VC for Eclipse, have already removed VC for VS, and nothing it's working.

 

Any help on how to proceed on this?

 

Best Regards
