@turbo07 after I sent in the ticket with the report I closed out everything and rebooted my compu. When I got back to WoWs the Game Center had returned to normal and the integrity check worked. I ran it and all appears to be fine now. I don't know why but when I sent the ticket it went to WoT customer service instead of WoWs. In any case whatever was wrong is corrected! Thanks for your concern.
