I think you'll find mp3Rocket on this list: Known Scam Sites (click on link)

If you enjoy supporting scam sites & keeping them financially affloat, then that's your choice I guess. If LimeWire didn't exist, then that program you're using wouldn't exist either (not in its present design anyway.)

At least from now on you can rely on their support only & not ours as we don't know about the bugs & abnormalities of that program & is not a recognised program in the gnutella community. And this is the Gnutella support forums.
