You can only have 3 activations simultaneously, and if you already had Pianoteq installed on a machine, but then reinstalled OS or something, you weren't supposed to deactivate it at all. It says so in the "Manage activations" part of your user area:
"If you will reformat or upgrade your operating system, you should not deactivate since the new installation will use the same activation slot.
Warning: Once you deactivate a computer, you will no longer be able to activate Pianoteq on that computer again."
