It's the same message as before?
Normally those access violation messages come with a number attached.
That number should be of use to you to try to perform a search in this forums with it, and hopefully find a solution.
If the number is not to be found anywhere, select yes to save the dump file, and send it to AryHann, following her instructions here:
http://hydlaa.com/smf/index.php?topic=27639.0She'll come back to you telling how the process is going.
You can also post the number here, and maybe someone gives you a valid hint.
The other usual crash source is due to text in description window.
Its workaround is to reduce fontsize through PSsetup, log back in, restore the changes, log out, restore font size, and rejoin again.
