Activation issue - licence has expired but is not true

Hello,

We have a problem with SDL Trados due to that it shows an error with license expiration, but really it should be activated. I have tried to desactivate and reactivate license, but an error appears with the following message:

"Provider error occurred, code 653.

Revocation is either complete or revocation proof is already uploaded"

We have a product key to be able to use the programa with 3 users or seats.

Please, can you help us?

Thanks
