alright, im not going to lie i dont really have any idea whats wrong. My Limewire wont connect, but i can search the web, talk on aim, anything BUT Limewire. So i went through the steps to fix it with the Windows XP firewall through the limewire website.... still no luck. Went through the steps to fix it with the Norton Internet Security through the Limewire website.... still no luck. Now I'm here, its been about 2 weeks and im very sad i cannot download music. If someone can help me i would greatly appreciate it. And im not that good with computers but if you can put it in "people" terms i think i can get it.

Don't use 2 firewalls together! Disable the XP firewall & just configure the Norton. Do you see the firewall icon (brick wall in front of the blue earth)?
LW might be detecting an internal firewall within a modem or router as well. Have a look through this thread. Double check your Norton firewall setup. Read the info about enabling UPnP & port forwarding, if your modem or router has it's own firewall then you should look at those as a fix.
Connection problems? Check here first!

Do this test & see if it works
