Hi cozzette,
 
Do you see the firewall icon (brick wall in front of the blue globe)? 
In LW go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session'...is it true or false? If it's false, you're not recieving connections from other computers. It usually means there's a firewall problem somewhere that's stopping people from downloading your files. 
Please give us your details.
