Just like Zanon above, this has been a massive problem since the last patch. It's progressed from maybe once or twice a day to every few minutes. I cannot teleport, change zones, talk to NPCs, receive trades, exit (or sometimes enter) cutscenes, walk in or out of the range of fates or various other things without the game just crashing with no explanation.

Reinstalling the game has had no effect. I have cleaned my registry as well as reinstalled various things such as drivers and even C++. My video card is a Radeon 6670, and my operating system is Windows Vista. Please send help.
