Vray Ple for Maya, not renew

Hi all, I have a problem with vray Ple for Maya license renewal.it expired on August 11, but if I click to renew it, the message

“You already have a V-Ray Personal Learning Edition (PLE) for Maya.
Your license is valid for 90 days and you can renew it after expiry.”.

How do I solve it? Thanks in advance​
