Steam help

Hey guys, need sum help with steam

I downloaded N: TW last night from Steam, which took over 24hours!!!!! I was shocked

When ever i click "play" the front loading screens comes up then it crashes

My computer i would consider fairly top of the range, it plays E:TW darth mods on max with out any lag

Any advice of fixing this so i destroy some frogs?

Moved to Technical Help.

Could you post your dxdiag or something?

It doesn't seem like a Steam problem, but did you close the comp or did other things during the install, that might've broken it?

Verify your game cache. 22.4gb downloads can lose something on the way.
