Like allot of you, also i have had trouble with the patch.
I tryed everything they said in the posts, but nothing helped.
I was near nervesbreakdown but there was hope..
I just Reinstalled the whole freaking game :(, and guess what ?
Everything is working now :)
Took me about 4-5 houres 2 complete all with download and update.
So if u still can't play an sick of waiting for the answer ...... RE-INSTAL
