Bioshock won't launch... D:

"Bioshock.exe has encountered a problem and needs to close. We are sorry for the inconvenience."

This is what I'm getting when I try to play Bioshock. I downloaded it on steam, tried to play it today (it's been playing fine before), and I'm getting an error that it need to close before it has even launched.

Does anyone know what I can do to fix this? I need my plasmid fix BAD.

Thank you in advance. If you need more info I'll try to help.

I assure you I am extremely sorry for this. I really don't know what to do and do need some help.

Is it possible to un-install and re-install Bioshock without

1: Losing my save Data

2: Having to re-pay for it

I'm pretty sure I can do #2, but If I can't that would be a cataclysmic mistake.

And with that second question... *sigh*

Bump.

I went and 'verified the integrity of game cache', and Defragmented the cache.

Now I get a breif 1 second flash of a loading screen before getting a new error:

Bioshock.exe –Application Error

The Instruction at "0x10c98aa7" referenced memorty at "0x00000000". The Memory could not be 'read'.

Click on OK to terminate the program

Click on CANCEL to debug the program

I'm really really sorry to be re-reposting, but this is the only forum I belong to. Can no one help?

Exact same problem. Justbought the game so my drivers can't be out of date.

I get the Bioshock splash screen, then nothing.
