Wrong contract expiration date after 8.5 installation

Hello!
I have a perpetual license that Expired on March 2016.
Today I unistall my  8.4 to upadate 8.5.
I deactiveted my license and then, after 8.5 installation I reactived it again. All worked ok!
But now when i start 8.5 I get this strange text "This software was relased past your contract expiration date (1/20/2016).
Please go to Avid Support Website for more details". So i can not use my Avid! 

Does someone know about some syncornization problem with Avid license database? 
What can I do?

Thanks
