2.6.5 is out of date -- you might try notifying support here
http://www.limewire.com/english/content/proform.shtml and see if you can get LimeWire Pro 3.8.5 for OSX
Pro is only good for 6 months of updates, so if you just got Ten for X,
http://www.aladdinsys.com/ should be giving you an up-to-date version I would think.
