Same thing happening to me after installing the latest version. I posted a topic about it on the 26th because I didn't see yours (no 'crash' in subject or message).

In any case, what seemed to make it happen less was to NOT select the 'immediate shutdown' option when exiting Limewire.
Since I can't have unstable stuff like this latest version trashing my system I had to remove it all together. I would love to have a working version again, but the general lack of response leads me to believe that if it's fixed at all, it will be under the radar.

No viruses or spyware related junk on the system either. Even tried it with a virgin install.
