Propagating Updates to secondary PCs

Hi there, I have been successfully running Multiplicity Pro on my PCs for a two years and have been regularily maintaining the updates thru Stardock Central. However when I Updated recently my secondary had some issues. As it turned out the protocol had been updated so I had to reinstall on the the secondary. Actually I couldnt find the the UPDATED install file so what I did was copy the entire contents (of multiplicity intall directory) from me Primary to the secondary and all was right in the world. I have recently added a third PC and I am wondering how I should proceed? What I have done (in the mean time) is to dowmload the latest Public install and run on the NEW secondary, however the nag screen keeps coming up when I turn it on. Any help will be appreciated. (addendum - I found post "help me understand the upgrade use-case better.." I suppose I coulde winge to the Authors to add weight to the "Push Updates to Secondary" Idea
