Use the advice in the * warning paragraph on this page:
http://www.gnutellaforums.com/mac-os...0-5-later.html about removing the
install limewire.pkg file from the Receipts folder.
BTW the newest version of LW you can use on OSX 10.4 is LW 4.18
Only intel computers running Leopard OSX 10.5 can run LW 5.
Thus, I would suggest you go to your personal Pro download page, & do as that first link suggests at bottom of page, get the older version LW 4.18
IF you forgot to bookmark your LW personal Pro download page, access it from here:
