The game client encountered an unexpected error and had to close.

I was told by a friend who had a similar problem to uninstall my graphics card drivers and re-install them, then to do the same for the game client. I'm doing that now so if it works I will post and let everyone know.

Well I've been playing for a good 3 hours and haven't had a problem, so hopefully that was the fix for it.
