I've got myself legit black ops 2 for pc. Anytime I try to install I'm getting "configuration data for this product is corrupt" and than "fail to run install services".Tried to contact steam help line but no answer whatsoever.Did some research online but couldn't find any help.I don't care that much about online play part so if someone knows how to pass steam or any other solution that would be great. Otherwise I don't even know if I can return the game I can't play. I'm running Win7 ultimate.
Thanks for any help
