I purchased the KVM upgrade yesterday and wow, I don't know how I managed without it. This is exactly the software I've been searching for.

Anyway the thing is I'm now considering upgrading from the standard KVM edition to Pro, so I can add a laptop and surface pro to be remotely accessed from my primary desktop, alongside the second desktop I have full KVM control of now.

I did discover this page here: https://www.stardock.com/products/multiplicitypro/upgrade.asp that appears to give the option I need but this generates an error after inputting the required information, so I wondered if it's possible for you to offer help with this upgrade.
