Do you see the firewall icon (brick wall)?
In LW go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session'. Is it true or false? If it's true then you can accept incoming connections & there's no drama. If it's false, there's a firewall somewhere which is causing a problem... very few (if any) people will be able to download from you.

The thread below has lots of info about firewall issues & their fixes
