so i enjoy limewire for my music anvideo needs haha.
but i use utorrent for my torrents but now that i upgraded my limewire to limewire 4. whatever it is it just downloads my torrents threw that so how can i make limewire not my default torrent downloader?

I presume you use Windows. Right-click any torrent file, then choose open with & choose uTorrent & click the always open with option. Then uTorrent will become the default program to open torrent files again.
