Directory gone wild

I was playing WoW earlier when my computer just suddenly froze, I thought it was just a small bug and rebooted. But when I had rebooted, I couldn't click on any of my game shortcuts, or my game directory shortcut. The directory is still shown and I can click once on it, but not enter it. Also, when I try to use the seach function to seach for the games or the directory it doesn't find anything.

Help much needed!

 

Couldn't seem to find an edit button so posting some updated info here. All the same problems persist, but I have some more info which maybe could help someone figure it out. The directory is still taking up disk space, although when I look at its properties it says it doesn't. I can make shortcuts of it, but not delete the shortcuts. I cannot change the name of the directory because it says it can't read the sourcefile or sourcedrive.
When I right-click the icons for the games which is in the file (icons are on my desktop) and look at properties, it still says that the target directory is the same, but I can't go there.

Any help? Sucks not being able to play anything :cry
