Problem with mods

[Zorn]

Civ runs completely fine for me - until I want to try a mod.
After the game restarts with the mod, it crashes with this message:

At first I thought it was a issue with the mod, but exactly the same happens when I load one of the Firaxis-mods, like the tutorial.

Has anybody a idea what is going on?
