I have a similar problem using the MCE Remote Plugin. EventGhost does not recognize the Remote anymore after resume or reboot. Devcon the Remote as well as Deact/act the Plugin does not work. Was is working is to Terminate and restart Eventghost, then the MCE Remote is working again.
Seems to me that the support of the Plugin services for these conditions in EventGhost is faulty!
Hope this helps you to fix your problem, and hopefully someone of the development team is looking into this problem.
