[Koinon Hellenon] CTD Before Battle Errorlog attached

After trying EB2 since a very long time again (while looking forward to the fun) I have run into a problem regarding the first major battle with a full stack army for Korinthos, very early in the campaign (270 BC). I had a frequent "Fatal Graphics Error" Crash without any logentries, now skipped the turn and tried again in the next one, this time the log was written. I have played EB I, earlier verions of EB II on this system without encountering any gamebreaking issues like this!

Please view the errorlog in this link for further information *removed*
