Try the connection fixes:

If none of those work. Uninstall LPE, remove the LW preferences folder. Then re-install LPE. LPE works best with a clean installation.

Make sure you make a firewall exception for LW.
Edit: good timing lol .. we both posted same time David91.

I won't say why, but the Mac connection-fix installer is actually better than the Windows one.

Not a lot of difference though.
