Just bought Multiplicity today, and the setup went smoothly. Got my desktop set as primary, (product key entered properly on my desktop), and my laptop set up as a secondary.
After about an hour or so, a message came up on my secondary saying no product key was found. I thought secondary PCs did not need a license. Anyone have any thoughts on this?
If the 2nd PC was actually set to a Secondary, no, it would \ should not be asking for a key. Are you certain it is indeed set as a Secondary?

Also, was this installed via Steam or a Stardock installer?
