Depends which Norton package you have. Check the Norton folder & see if there is a firewall there. If there is, then choose between either Norton or Vista's firewall to use & disable the other one. Add FW as an exception to the one you decide to use; Setting up an exception for LimeWire/FrostWire in your software firewall (click in link). Simply add FW instead of the suggested LW.

Set FW to run as administrator by right-clicking on the shortcut to the program.

If you have not used FW in a while, perhaps you need a fresh gnutella.net file. Try the tips here: If LW 4 Will Not Connect (click on the blue link). Of course, these tips apply to both LW & FW.

BTW your Java is not the most recent. Sometimes it can affect connection. Java Downloads for All Operating Systems - Sun Microsystems & choose the Offline installer.
