I went through all that hell already, problem was just a corrupt save.
I loaded an earlier save and the game loaded. I should have known to try that first rather than going through the uninstall / reinstall thing... I hate when I get momentary tunnel vision.
Not saying that's what your problem is, but I'd try loading an earlier save first.
Yeah, you lose what was on the bad one, but it's better than doing all that other stuff.
