Anyone familiar with the above?

Is it related to Limewire?

Yep, been discussed on forums some years back. It's a fake. You can only download as fast as your fellow sharers allow you to. Speed up utilities like that are just a name with fake abilities. In fact, a previous version caused ill effects on peoples computers. I am sure this is the same or similar. And connecting to others is up to the network & personal settings, it is not the same as downloading from a web site where download managers can be used.

Thanks mate. I've not been on here for quite a while but it's very reassuring to see you're still around!
