I've been using free Limewire for quite some time flawlessly. Now I've bought Limewire Pro and have had nothing but hassles. I'm on a Duel Processor (2x 2.5 GHz) Mac G5 running Panther. Are you on same by any chance? I've tried to ask Limewire but have had no response from them.

Do you use the Resume function on many files by the way. Do a search on the forum for Resume & eventually you'll get the idea.

May I suggest you try 2 things, one by one:

Delete LW's Preferences called .limewire & found here: /Users/your_username/Library/Preferences/LimeWire (note: you'll need to reset our options so it might be wise to make a note of all your settings.)

Re-install Java using only the Standalone Java installer

After installing any softw in OSSX you should repair permissions: SAFE start & repair permissions
