I was patching the game to version 1.07 and at about 85% through the patcher went unresponsive. I tried running the patch again and it told me it was not meant for my game version. I then launched the game and it goes at least to the main menu where the game version is 1.07 but I am worried this is going to bite me in the ass later on if I start playing. Anyone got any ideas how I might avoid reinstalling this huge game and the f---load of patches again.

EDIT: Any ideas as in, is there a way to uninstall or downgrade patches?

EDIT2: Well tested actual ingame and loads of models are missing, buildings outside walls are invisible and the lighting is bugging out...
