Also just another forum member:
I just had this happen as well, and, honestly, what worked was go and make a sandwich while it finish loading. Don't remember it hanging for so long at any point during the loading before (though I think I stopped playing last before the last patch, so it might be that) but eventually, after a minute or two of being non-responsive, It got past that point and finished loading the game. Rebooted just to double-check that it wasn't just luck and I think it even did it a bit faster that time as well.
Did reinstalled, cleared mods, etc before I tried the "just be patient" route, but if that hadn't "fixed" it for you, it probably had nothing to do with it working for me either.
