I am posting this as it helped me, not sure if it's been mentioned (as I briefly read over some of the replies here).

IF you think it's possible CC issue (Mine was, i used this and it plays like an entirely different game), this is also easier then deleting all of your cc.

I ran the program, deleted the .package files that were the issue. May help some of you.
