360 Share is not an agreed part of LimeWire. It is a copied version & the code has been partially changed. As said they normally offer their software to scam sites. You can find it mentioned at the bottom of this post Known Scam Sites (click on link) It is apparently similar to Etomi. They don't have a proper support site. We don't know much about their program other than what the gnutella community have told us about how they have copied the code & are not a part of the main gnutella community for development. We on this forum can't support something we don't know much about. Nor do we know where you can get free Pro versions of it from. Sorry.
