nope maybe thats the problem, it won't even let me load that game now!
Sorry don't understand, do you mean you can't start a new campaign, or that you can't load your saved game?

Shadowing makes western roman rebels take over western roman cities if they rebel, ie. that is what causes them to be 'resurrected' in the original game. I had assumed your crash was to do with western roman city rebelling, and triggering shadowing effect.

When did your crashes occur? (ie. please specify: on AI go, loading battles, moving over strat map, etc.)
