Have been using LimeWire for the past three weeks and I am fairly happy with how it works. Will revert to ver 4; hopefully I won't have any problems doing that. Seems to me; I recall that any time I have wanted to revert any program back to an earlier version, it would not let me do it!
I have never had any problems downloading from any P2P site. If it does ever happen; there are always other torrents!
