I'am also having the same problem. It used to be I could reboot my computer and Limewire would be just fine. But now I can't do anything on Limewire. No searches or anything. It's really frustrating.

VonneMarie,
Try deleting LW's preferences folder when LW's closed. See points 2 & 3 below for instructions
Fixes for LimeWire

If that's no help, post your details

Thank you Birdy, but it didn't work and I don't know all of my details to even post. I'm not to computer savy.

I'm screwed.

Well, you're screwed if you don't let us help you.
Can't you answer any of those questions? It's up to you if you don't want to bother, but if it was me...I'd at least have a go.

I have Sunbelt kerio personal firewall, cable modem, Limewire 4.12.6 and windows 98.

Where are you connecting from (house, apartment block, school, student accommodation, work)?
Who do you pay for your internet use (that's your ISP)?
Have a look on your modem...what's the brand and model number? Have a look underneath the modem as well.
How many green connection bars do you see in the bottom left corner of LW?
Do you see the firewall icon (brick wall in front of the blue globe at the bottom of LW)?
