I'm also having the same problems. I was able to use limewire before but all of the sudden it tells me that I can't connect to the server.

Here are my specs:
Windows XP
1 gig of rams
Cable Modem
Isp=Optimun online
Over 200 gigs of Memory
I connect from y personal computer
I have windows firewall and have limewire open so I know is not my firewall.

this is a new problem and I'm experience users. I also like to add that I'm having the same Problem with Ares lite. Another peer to peer network.

The test result come back true.

I answered every question to the best of my ability. Any help could be usefull pls.
