I have never had any problem using EB in the past.

However...

A while ago I put fanatics mod it. I then suffered CTD's, so I uninstalled everything and the game seemed to work.
Except (playing on ALX) I got a crash when looking at the roman faction leader after a while, so I killed him.

But whenever I fight a battle I get a crash with no error message.
The first time it was to do with me running out of disk spce, but I now have more space and it happened again.
And ideas?
