Apparently the new patch they put out is causing 360s (not sure about PC or PS3) to lock up when trying to play the game. It's all over the BSN 360 tech issue threads and so far no word from bioware. So far it makes the games unplayable.
I wish i'd posted it sooner on here. Apparently you can remove the patch somehow and play with the internet unhooked but if you're into MP then it's no good. QC at bioware and microsoft seems to have missed something as MS has to playtest and okay anything going out over their network and i'm assuming Sony does too.
How many ways are they going to screw up this game?! Its unbelievable. It really doesn't affect me though because I have not touched the game since I beat it and don't intent to get anywhere near that game before they add those end cutscenes sometime in the summer but im not holding my breath.
The key is to turn off xbox live and play single player that way. which is fine if you aren't after the achievements but MP folks are out of luck. It's getting grumpy in the tech support thread yet it hasn't bled over to the other forums just yet.
