I have been downloading using Limewire beta 4.9.5. I do not see any improvement from the previous versions. Downloading still slow 0 - 1 KBs and it still goes to "waiting on busy host" after a few minutes. What should I do to optimize it? May I know the difference between this version and the previous one? Thanks

As I've said, it's just as slow as the previous versions. Unfortunately for me, when I upgrade to this version, all my previous downloads are back to 0%. Does that mean that each time Limewire is upgraded to a new version, all the previous downloads need to be downloaded again from scratch?
