Random Crashing FTW

[dreamshadows]

On the birthday quest I keep crashing when I try to use the magic whistle to get off of Orlean's desk. I was on my assassin. I tried logging back in, crashed again. I had to get on another computer to get my character out.

Same assassin, same day, I went to try to access the Brasilis field map (or dungeon), whichever is the portal on the top right corner. Crashed again. Logged back in, and it wouldn't let me get to the screen before it crashed again. Once more, had to go to a different computer to get it to work.

I've patched the client as best I can, and I'm not sure why my machine is having problems. I'm running Windows 7 if that helps any.

Thanks in advance for any suggestions or help.
