I'm not sure what I did recently that could cause this, but any game I try to open and play says it can't be found. All of the games and applications are all installed and showing up in my game libraries, but when I click play I get an error message that says I can't play because they aren't being found. This is really strange and i am not sure what was the cause. It says try reinstalling to fix the problem, but that would literally mean doing that for each program. Has anyone else experienced this? The games even go through the motion of downloading and installing the updates for them, but once I click play to launch it I get that message that they are not found. I might try a system restore.
