Well, I hope someone answer me this time =/

Here's my situation:
I've checked my ISP to see if it blocks any ports, and they've denied it all. Then, I found this great(?) program on the Internet called PortDetective (www.portdetective.com) and I did a test with it on port 6346... Guess what: Says its opened. Even when I open LimeWire and try to connect, if I scan the port it will say its in use. So my guess it can't be anything about 6346.

My error is that I just can't connect, all i get is a message that says Connecting... and it never connects. Does ANYONE OUT THERE know ANYTHING about this?
