WOTLK Crashing while playing on Macbook, after around 30-40minutes playtime.

I am playing WOTLK on the Icecrown server and after 30-40 minutes it crashes with an error message. I do not know what to do about this. Can anyone help me? I downloaded 'porting kit' to get it working on Macintosh. Could very well be to do with that but that's as far as I can go.

The error messages comes up in a small box titled 'Wow' and states:

This application has encountered a critical error:

ERROR #132 (0x85100084) Fatal Exception
Program:
Z:Userscalvin|Games)World of
Warcraft 3.3.5aWow.exe
Exception:

The instruction at "0x682509BE" at "0x0000225C"
referenced memory
The memory could not be "read".
Press OK to terminate the application.



There's a black box that loads up along with WOW and it shows this information

I have the same problem with Porting Kit running on Mac.
If somebody got an answer to that Id highly appreciate that.
