i've tried everything for the connection but i still get an error message saying it can't establish an internet connection but i'm on my school's internet and i'm always connected. help please

As Grandpa said in your other posts...maybe your school has started blocking p2p. Have you asked network/computer admin if they've started blocking p2p? Do other students use p2p successfully?
Do this test & see if it works. If it doesn't, means that LW's default port's being blocked

You could try using the forum search to look for school connection or something similar.

when i try that it says your test has worked! i think limewire just isnt' working tha tmuch anymore.
