Game crash when starting game in mod menu

[Feanorz]

After I press "Start game" the game crashes, with an error about "cvgamecorefinal release.dll". This only happens in mod menu, normal games start without errors. I only have Civ V Unofficial patch and Vanila Enhanced installed.

System specs:
AMD Athlon 7450 Dual Core
2GB RAM
Nvidia GeForce 9600 GT graphic card
