Wait! I'm having the same problem, how did you solve it? I have a Mac OSX and I'm trying to download Limewire basic, so I go through the whole website (get basic, download for Mac OSX), and it downloads and pops up on my desktop as LimeWireSoftOSX but when I click on it it tries to open in excell for some reason, no installation option ever comes up, and it ends up quitting excell before anything happens. I used to have LimeWire and this all worked out fine but I had to delete it off my computer, now I can't get it back!! I've been trying to fix this four HOURS. HELP!!!
