Ever since I got CityMod, my game wont run

[Kelp]

After downloading the City Mod, all my game will do is tell me it's performed an illegal operation. This is crazy. I'm not saying anything against the creator of the CityMod, it's not his fault, but something must be really screwed up with my game. Has this happened to anyone else?

I even reinstalled it just now and it still won't run. It's like permanently screwed up now. I had the patch installed and Modswapper and everything. Does anyone know what could be causing this?

Did you get the regular City mod or City mod 2, because from what I know, city mod 2 is the one that works for Call to Power 2.
City mod 2 is on martin guehman's( spelling most definitely) site. If you have city mod 2 then I don't know what's wrong.
