Whenever you have a problem with the appliance, simply reinstall it (and WMP). It fixes pretty much everything and there is a reason you have all your files in Dropbox.
To connect to a host-only network you have to create a host-only interface. Select "File" -> "Preferences" -> "Network" -> "Host-only network" -> "(+)Add host-only network."
Make sure that you've followed the instructions.
