Luckily I am fluent in newbie. Correct me if I am wrong but I think it goes something like this:
You enter your login / password and then it crashes and gives you a prompt to save the diagnostic file (dmp).
And when you tried to troubleshoot it by loading in fullscreen your graphics settings, or card, or both together can\'t handle it and it doesn\'t display correctly.
\"full screen mode just a black screen?

??\"
Save the dmp file and post it in the thread:

Supposedly there is a new client coming out (even after the 0.3.007?) and this will fix 90 % of the bugs / crashes. However if your impatient you can try:
a) Changing your graphics settings (as it shounds like this might be causing it), or
b) Uninstall then reinstall.
Goodluck.
