So... This happened couple days ago, I tried some things here and there, and reinsatlling was my last option. *Uninstalls* *Proceeds to reinstall* BAM! http://imgur.com/TVQvFOx This again... halp pl0x
*Points finger at Velicc* HA-HA I feel your pain man. Only thing I can suggest is try downloading the old Steam version and let the patcher update it that way.
Hmm....send in a email to tech support only thing i can suggest. I'm gonna be doing a clean OS install tonite when i get back from work. I sure do hope i don't run into that error u got.
