I dumped Limewire months ago and have been using Acqlite, Acquisition and Poisoned with good results. I thought I would give this another try based on some of the reviews below. I downloaded, installed and all seemed fine until I click the "later" button when asked to upgrade to Pro. Then the program crashes immediately. I went to the Limewire site and found 3.6.15 was out and had "addressed" the 10.3.1 Panther issues. I downloaded and installed it and got the same thing. I'll stick with the 3 above for now or maybe forever.
