I installed Monday Night Combat. On first time startup it installed Nividia PhysX. It was on Step 4 of 4. I clicked cancel because it was taking a very, very long time. Now when I try to boot up MNC it wont start. I re-installed and it still dosen't work. Do I uninstall PhysX? What should I do? (I seem to have problems with like every steam game. -.-)
