Revoke of License Failed...

We are an academic institution utilizing Visual COBOL for a class...

Description: While testing product for academic use installed license on Windows 7 and now cannot revoke the license from license manager. Ger a "Revoke failed"
 
Also received the following pop-up:
 
"Unable to revoke all your licenses. Revoke failed for SolarManagedChecker.\nPlease contact Micro Focus SupportLine \n: Error[124]: Revocation not supported for trial licenses. Please contact Micro Focus Support Line
 
If we could get some help getting this license properly revoked so we can set it up on our production server I would appreciate it?

Thanks,

-Jeff
