Unable to keep connection
 

I've had Lime wire off and on for a while and never had any problems. However today I downloaded LimeWire 3.2.3. and I searched for one song and got it ... but I looked down and saw that my little light was red, and at the top it said I was disconnected. The problem I'm having is that I continued to download the song. I tried to hit the connect button but it never would connect for more then a few seconds. What do I need to do to get a connection?? I'm running Windows 98 SE ... This is the same computer I've always used with LimeWire without problems ... I just don't understand what's diffrent about now? I have no firewall ... or anything like that .. and I'm on the same cable modem as always. If anyone can help, I'm open for trying anthing to get this to work. Thanks.
