I have exactly the same problem too.
Was working fine till I updated the game on one of its earlier patches 2 weeks after it was launched, and it keeps crashes whenever i launch the game.
Works again whenever i uninstall-reinstall- patch the game, but the same problem will reappear after i switch off the PC...
Thought that it's because i'm using an old graphics card, and just bought and installed an MSI GeForce GTX650, and i still cant launch it...
Please help : (
Thanks and best regards
