I'm having trouble with my limewire as well. I thought that it was a problem with I tunes blocking it b/c I updated at the same time it stoped working. I have the new frostwire.

I downloaded the latest update and installed. I also checked to make sure that the file was not in my reciepts folder (and it wasn't there)...Still is not working. Won't start at all, it just bounces in the dock once and then stops.

Any other ideas?
