I haven’t used LW for over a month, I used to be in a house, now I’m in a dorm, I have the same ISP, Yesterday I went to use LW and it was having this problem of not connecting, so I updated, still the same problem. Then I searched all the forums and tried everything to fix it, still no luck. Here is the list of what I have tried:
CHECKED FIREWALL
DISCONNECT/RECONNECT LW
UPDATE/REINSTALL JAVA
UPDATE/UNINSTALL/REINSTALL LW
CHANGE LISTEN ON PORT
DELETE LIMEWIRE'S PREFERENCES FOLDER
DISABLE ULTRAPEER CAPABILITIES, DHT & TLS
If a "how to fix-it" was posted on this issue, I tried it.
