I was able to play the first three episodes without a hitch but when I try to start episode 4, the "previously" recap animation starts off a bit stuttery and out of sync but then smooths out until the recap is finished. After that, my system locks up on the loading screen and only the task manager will get me out of it.
However, even though the program is closed, my system will be stuck in a cycle where it freezes for a few seconds and then runs for one second and only a hard reset will bail me out.
FWIW - my Steam copy of Batman Arkham Origins will do the exact same thing as well but i was able to play that without any problems before as well, so it appears that an update or something I may have downloaded or installed has changed something.
Any help or suggestions would be appreciated!
