Do any of you see the firewall icon (brick wall in front of the blue globe)?

Within LW go tools > options > bug reports > view example. Now scroll down to 'recieved incoming this session'...is it true or false? If it's true then you can recieve incoming connections & there shouldn't be a problem. If it's false, there's a lot of info within the sticky below (check out the bits about enabling UPnP/port forwarding in case the problem's a router firewall)
Connection problems? Check here first!

Remember the network's huge & so you won't see every shared file around! You could always try direct connecting, then browsing each others files to see if your music shows up. For this to work, you'll all need to have Chat enabled & not see the firewall icon
