ugh! i haven't reinstalled or upgraded, but it is happening to me too. does anyone know if mac osx users can use kazaa? i looked on the site, but couldn't find anything about compatability. it seems that if someone had an answer to this problem, they would have posted it. i am not about to buy limewire pro, only to find that it doesn't work either. i was using this version successfully for about three months. ANNOYING!
