If you see nothing on LW's Connections page, means you're not connected to any other users. Sometimes you might see attempted connections there, as LW tries to connect.
Try clicking File > connect. Or File > disconnect, wait a few mins then File > connect. Make sure that in LW's tools > options > connections 'connect on startup' is ticked! Click Apply to save any changes within options.

If that doesn't help, make sure that you're only using 1 software firewall & that it's configured to allow LW. Read through this sticky, there's a lot of info about connection problems.
