Well, i've had limewire for a couple of years, never has been a problem, since a couple of months ago.
Heres an application for whoever is so kind enough to assist me through my problem.
1. OS version?
Windows XP.
2. What firewalls you have? BitDefender (i added the rule to allow limewire)
3. 512 MB RAM
4. 95.5G Available on hard disk
5. Connection type : Broadband
6. I'll find Model numbers out if its necessary
7. Im at : Home
8. Version : 4.18.2
9. ISP : BT
10. The test Worked
Also, on limewire, the little firewall picture DOES have a brick wall through it, but its always been like that, even when limewire worked.
Peace out
