Europa Barbarorum

I have installed EB and managed to load up the main menu but when i go to start a campaign it keeps crashing.The historical battles work fine. i can get to the menu where you choose your faction but when i click start it crashes. in the faction info it says something about activating the campaign script, i was wondering if that was the problem, if it is could anyone tell me how you activate it.

No, that's not it. You need to use the original executable to run the game, not the NOCD one. If you are using the original executable, run a validation.
