First off let me say gNet is a very cool world indeed. I am new to peer2peer, not new to Macs - I installed Limewire Pro (3.3.4) and after installing I got directory errors that only 3rd party software (DiskWarrior) could repair. Interesting I still have not seen mention of this on your website, this is not a known issue I guess ?
Mac Fixit seems to be aware of this... weird.
peace.
