I can't get limewire to start on my computer. I download it off the internet, and then an application appears on my computer saying to click if I want to download it, and that runs, and says it's complete, and then nothing. i don't know how to access limewire from there. nothing appears, and if i click on the limewire icon on the desktop, it just asks me to click to download it, and it never seems to actually be installed on my computer. Ideas? oh and i'm using a mac
