Friend has this problem. All he does is reboot his computer and starts fresh. His goes all wacky after playing another game then going to WR. But once he reboots his system and goes straight to WR the game plays fine. He says the clue to knowing if you need to reboot is when you go through the SOE splash screen and you see the bottom of the screen flicker, you need to reboot.
But that is his system. It might actually work, give it a try. Worst that happens is that you spend a few minutes waiting.
