lime wire pro error type 2
 

I just downloaded lime wire pro BUT i'm getting an error 2 message and i do not know what to!?!? I get to the help button and it logs off instantly. It then asks to specify a port in the config window but i cannot locate that window!?!?
Also, with the free version, iTunes would automatically play the downloads - now it does not.
This system was working fine but the new download has screwed up my mac!
HHHHHHHEEEEEELLLLLPPPPPPPPPPPPPP
