Hello, after playing FC2 well from my DVD for more than a year I switched over to get it from Steam & played well for about a year, all of this was on my old puter running XP. Since 11/2012 I've run it on Steam & my new puter with Win7 & had few problems until a week or so ago. I was playing a little ways into the second half of the game & it froze up & I got a small window after hitting Control/Escape together, but I had to restart the game or the puter to get a full screen again. Within an hour or so of gameplay, it did the same thing twice again. Then after the third time, couldn't get a full screen on restart.I uninstalled/reinstalled twice & attempted an install from my DVD, all failed to launch. I'm successfully playing Crysis, Graw2, Dishonored, Rage, & several more, most all on Steam.
