Problème lié à la licence

I bought a 3DEXPERIENCE for student ENGINEER and 3DEXPERIENCE student Designer license with a license that has already expired with the same account as last year, the problem is that when I launch the 3DEXPERIENCE application to be able to start working, a message sent me telling me that my license has expired, and I don't have the ability to create parts due to a license error,  thank you,
