I have three versions of limewire. One is unknown, one is 1.8 and the other is 2.2.1. But they have one thing in comman, the're all not connecting! I look in the connections window and they are no connections. I don't know any connections. All I wanted to use limewire is to download music and movies, but I did not know it would tons of bugs.

First, these aren't "bugs". It's probably just a temporary problem with the host cache that Limewire connects to by default (you can add backup host caches if you want, or you can just type in the ip address of any stable gnutella connections that you know of). Second, this isn't a problem with Limewire, it is a problem with the host cache. Any gnutella client that uses the same set of host caches would also have the same problem. Next time, don't be so quick to bitch and complain. Do a little research and you might gain some usefull knowledge about how the gnutella network and it's clients work.
