Oh, of course. I was just annoyed earlier and I have very little patience. So get this, my anti-virus software (which I had disabled) had quarentined the launcher files for New Vegas as malware. However deactivating it didn't restore them so I assumed I still had a problem. The issue here is that theres no particular fix to this issue, its just a generic error message that could be caused by a billion things. Anyway, fixed it, played happily. Love u Steam. Ok, so tell us what you did to fix it, so someone else doesn't have to go through that.
