Hey all,
So I just bought the Urban Warfare DLC and now my game is locking up when I try to start a new game.
Anyone else with this problem?

There are a few of us like you. Does it hang on teh loading screen? I have put in a support requrest and hope to hear from them this year. ;)

If you use Galaxy, you can always try Verify and Repair, if you use installer, you can try a new clean install and hope it helps. I only encounter some colour glitches every now and then with the new patch and else rarely a bigger lag.

I use galaxy and Repair never got off 0% checking so I fully re-installed and now it works.
