Hmmm didn't know LotR had one of those. What's a tizzy any ways.
But it seems some users have been having problems with new updated drivers from ATI for there Radeon series video cards.
Might try and roll back the drivers to the previous ones, if that happens to be your video card maker.
I would also suggest you use the search (upper right between f.a.q. and home) and search for fixes for LW.
