I did what you suggested and I got the same message.

" Unable to attach "LimewireOSX.dmg" - not recognized. Just as I did before.

I trashed my original Limewire instead of uninstalling could that be the problem. I can't download just an uninstall can I ?

I down loaded other dmgs today just to see if they would open and I didn't have any worries with those. I found Cabos-0.6.6MacOSX.zip but I didn't download it because it isn't a dmg. I don't want the application, it is because it seemed as though it was a similar type of program that I looked at it.

Thank you
