Arma 2 crashes as game starts steam version

Right, hoping someone can help me, here is my problem,

Arma 2, loads fine, I select game and everything loads up, I select my soldier type and then the game goes to load, the green bar comes on saying loading and just as it gets to the top the game crashes back to the desktop, saying it is unresponsive, now the game has been fine and only started it last 2 days, I have uninstalled and reinstalled it twice and same issue, I've also uninstalled battle eye and reinstalled it, still no good, no idea why it is happening, frustrating as hell. It also gives me an error when and when I go into it it mentions bclient.dll, this is why I uninstalled and reinstalled that, but no good, Ive also had suggestions it is something to do with my steam account and try to run it in admin mode, which I can't do as the is no option, I am on 32 bit computer, when I go to comparability mode I don't have the option to run in admin mode..any help will be much appreciated
