Ok, so I recently downloaded Frostwire because my Limewire seems to have stopped working. I managed to download all the stuff I wanted to. But when it came to transfereing it to my Itunes Library It didn't happen, Instead I get a message that comes up telling me that it is not a valid podcast URL (its not even a podcast), next to the song is a weired symbol like an upward facing sound ripple and where it supposed to say how long the song is it just says 'continuous', what is going on, is it to do with the compatibility? or something. Please help, I WOULD APPRECIATE ALL INPUTS.

I have the same issue. Can anyone help please?

Try adding the song from your FW saved folder, rather than from FW's library. The thread below has more info (it's referring to LW but should all be the same for FW)
