Hello,
Sorry to hear you are having trouble.
I lose the connection to my windows 10 pro laptop when the lid closes. Windows 10 power setting is to do nothing when the lid closes. Kind of defeats the purpose of Multiplicity if I have to have two monitors on.
Can you still ping the Secondary when the lid is closed? If not, Windows is powering down networking - something MP needs.
