Trouble starting game
 

yesterday, i was playing for awhile and i logged off. later, i tried getting on, but it said could not launch game. anyone else having this problem?

Had that before and had to re-download and install the whole thing again.

Some of your game files were corrupted. If you can isolate the files that were corrupted, you could replace them without going through reinstallation.

That may or may not take longer, depending on your download speeds, or if you have the patches.
