Help with Steam

I purchased the game oulast during the steam summer sale, but i was waiting to play it with my friend brice. I have had it downloaded and installed ever since the summer sale. i tried to open it last night to play it, but it wouldnt open! i tried to open it again and it told me it was already running. There was no icon, and it didnt even show up in my task manager. I deleted it and redownloaded it, but the same thing happened. I checked the forum and a bunch of people had my same problem. I couldnt find any solutions to the problem though. If anyone knows how to help me please do. Thank you for your time and consideration

Did you try 32 bit mode?

If you're still having problems you could also try to verify the integrity of the game cache:

Right click on game in steam library>properties>local files>verify integrity of game cache

It can sometimes clear up stubborn issues.

verified the cache, did nothing. changed to 32 bit, couldnt get past the startup logos... i guess ill just email them
