licence key error message

Hello,
 
We have licence SaaS Starter License with Premium Support for several domains including ********
Licence key is configured for *********
When flexmonster is run following error is generated "Current key is only applicable for ********........
You are trying to use the following key: **************************************
 
Please advice how to solve this issue.
 
Could you please also check the licences keys we have for domains
*******  and ******** ? Keys seems to be exactly the same.
 
Thank you.
