I'm having the same trouble. I can download audio files, no problem, but when I try to download programs I wait 2...3...even 4 hours and once they are downloaded, I can't find them. When I do a search on my computer, it finds the files (that I can't view in my shared folder) and when I double-click to open them/unzip them it takes me back to LimeWire. Very annoying.
Any help would be greatly appreciated!!
