Do you know who your isp is? Ask them how to... re-set up for connecting!

Hold on how did you post here if you have no connection ... let me think about that.

If you only mean that LW is having problems connecting, then we will need a lot more detail.

Please answer these questions: 1. Connection type, 2. Modem & router brand name & model numbers, 3. Where are you trying to connect from (home, school, work, etc.)?

Make sure your Java is up to date: Java Standalone installer solves a lot of issues.

Whilst LW is closed try deleting LW's Preferences called .limewire & found here: /Users/your_username/Library/Preferences/LimeWire
