Im playing as Rome stuck on 632AUC on steam version it either gets stuck on Dacia turn and or Armenia turn. I have 2.1a version of RS2. Im playing Cod Black Ops on full graphics so i know that has nothing to do with it. The Error is:

Runtime Error Program:...6)/steam/steamapps/common/rome total war gold/rometw.exe r6025 pure virtual function call

please please help it was doing it before i downloaded 2.1 and its still doing it so i cant play and im not going to start over. I just got done dealing with the stupid civil war and i hate empire total war!
