I've started playing World of Warcraft again after being away from it for a while. After getting the 3.3.0 patch, I tried logging in, and my whole PC freezes up on me. I've tried updating my flash player, DirectX, and even have gone so far as to uninstall and reinstall the entire game. Now the 3.3.0 patch won't install properly, and even then, if I try to bypass it and go into the game to pick up the patch directly instead of through the launcher window by attempting to log in, my system still freezes up on me. Any advice on what to do?
