Thanks for the reply. It's not the Limewire .dmg that won't mount...it's the items I have downloaded with Limewire. Some items work fine, but most give an error "no mountable file system".

I have tried downloading many different versions of one title and have yet to get one to work. I have also tried moving these files to other machines thinking maybe it was something with my system. Nothing seems to allow me to open these files !
