Fabion's on the mark I think. A good registry clean out. If you don't have one perhaps one from this indirect page: http://www.gnutellaforums.com/showth...232#post121232

If you open LW, Control, Alt & Delete & open Process Manager & see how many limewires are listed. This could also be an issue. Unfortunately, versions of LW prior to 4.4 had to be removed via add/remove control panel. So the auto-remove that happens on the new installer doesn't work on the older versions.
