Are you able to connect using other internet applications?

Reason I ask is I'm not sure which computer you are using to connect to the forum here.

I was just looking around in 1) start 2) contol panel 3) internet options 4)secuity 5)restricted sites 6)sites. This will provide a list of all your restricted sites. Make sure LimeWire is nor listed there.

Also check your Network connections see what it says under LAN or Highspeed internet. I have a 1394 connection (1394 net adapter)listed there and Local area connection (Broadcom NetXtreme 57XXX 1 Gb ethernet....), Both are showing connected.

Make sure it (they) are configured properly. If I recall correctly I had to reconfigure the net adapter when I went from dialup to highspeed.

Just a thought
