I have no idea. What do you think is going on?

Clearly something has changed since yesterday - what do you think it might be?

If you read through the forums you will find a link to Taliban's connection file - follow the instructions, this may help.

Or you could try entering 'router4.limewire.com' into your connections tab (you may need to enable it first from the 'View' menu option).

A little more information would make it easier to diagnose what your problem might be:

Operating System?
Java version?
LimeWire version?
What excatly are you doing?
What exactly do you see?
What do you see under the connections tab (take some screen shots)?
