Having received your keys for full licenses for Server Express, it appears that they will expire in x days.

There are two different model types for Server Express and Server for COBOL licenses; model 1 and model 2.  These different model types only really apply to the runtime product, Server for COBOL, but not the compiler product, Server Express.  If you encounter this problem, it is likely that the license keys shipped to you are model 2 type. 

In order to resolve the issue, contact your Micro Focus sales representative asking for the model 2 keys to be converted to model 1.  Note that this is a purely commercial issue and cannot be resolved by your SupportLine representative.
