...but two days ago I was connecting to LimeWire and downloadind, happy as a clam. Then for some reason I can't connect to LimeWire; I tried to telnet, but never got the "Gnutella OK" message, which supposedly means that my ISP provider is blocking the connection. But I was connected only two days ago, and another person with the same ISP is connected to LimeWire now, so what should I do??

This is just a hunch, but you're not the only one. I havn't been able to connect for two days and from what I've been reading, niether have a lot of other people.

I suggest you contact the other person that can connect and compare the settings in your Tools | Options | Connections quick connect window. Just as an FYI I an connecting fine... using Limewire 2.5.5 / Win 2K. - Here are the connections in my setup, which I believe are the defaults.

router.limewire.com:6346
connect1.gnutellanet.com:6346
connect2.gnutellanet.com:6346
connect3.gnutellanet.com:6346
connect4.gnutellanet.com:6346

Well, the thing is that I checked the telnet settings, and I have all five, natch, so I'm at an utter loss. I tried doing the whole Freewire fix that someone else here suggested, but since the connections are the same, nothing happened. Is this a problem with the ISP or with the Limewire program (I'm just a molecular biologist, and computer lingo makes me run like a scared bunny, so pardon my ignorance)?

If you are not getting the Gnutella OK then the particular connection needed to succeed is not making it. There can be several reasons.

- Are you running any firewall software
- Do you have a hardware firewall
- If you are on an academic or Business LAN is your system administrator blocking traffic on port 6346.
- If you are using a public ISP is your ISP blocking traffic on port 6346.

Since you know of another pserson on the same ISP is OK it is still possible that a given router withing your ISP is blocking you and the other person may not be going through the same path... I think a phone call to your ISP would be in order.
