Unable to Access Lobby - 'Disconnected: Detected Data Mismatch'

Back from a year break.. It let me in firing range just fine. An hour later I shut down my PC and re-logged a short while later and now i'm getting the same error..EA support is no help either, does anyone know what's going on? Kind of sucks, i have 10 heirlooms and a lot of hours played on this game
