I'm having a big issue playing campaigns, after finishing up a nice campaign with Greek Cities I tried a Gallic one but I was getting random ctds on campaign map, I tried a Roman one, same thing happened, then I tried a Seleucid one, same thing happened. For some reason multiplayer online battles are still fine, but my campaign is screwed.

I've been looking into it for a couple of days now but no joy, I'll keep trying but if I'm not sorted before its my turn I'll have to pull out :(
