Can't connect with Limewire or Napster

[fbartell]

For several weeks I was happily using Napster. Then I downloaded Limewire and installed it. Since then neither has been able to connect to anything. I've done the whole uninstall-clean-reinstall bit several times to no avail. I'm connected thru a LAN, using Novell to the College server which then ties in to inet. I have no problem connecting to the internet. One person on the napster forum suggested that a registry flag has been set to an off position, but when I tried regedit, the network informed me that "registry editing has been disabled by your administrator." Since they wouldn't like my 'wasting' time by downloading MP3's I haven't talked to them about it. Help!! Any ideas greatly appreciated.
