Game Crashes and More

[RegretZ]

Okay, so as most of you know I just switched to Ubuntu Linux.
I managed to get Graal up and running, with help from a friend. I always keep both, v5 and v6 just in case.
A lot of things won't load for some reason, including bodies.
It may just be my pc, but it also crashes every time I get on Zodiac. Not immediately, but within a minute or so of logging on to the server.
What's going on? And does anyone else have this problem?
It happens with both clients by the way.
