I had every single download problem mentioned on this thread. It all started when I downloaded the latest version of Limewire Pro. I had multiple Q & As with Limewire service and support, but nothing helped. THEN I DOWNLOADED LIMEWIRE BETA and ALL THE PROBLEMS DISAPPEARED! The download speed was faster than ever and all the softwares functions worked. I run a Mac G4 and G3 with OS10X, so I only hope that downloading the new BETA will solve others users' problems too. Good luck!
