First, please be aware that these are user to user forums (so public), not a contact for Magix Support. So confidential data like order or serial numbers and personal email addresses should never be posted here.
To resolve the error you are seeing, sign into your Magix account, go to My Products, find the listing for PS and check how many activations are listed. My suspicion is that you have exceeded the maximum number. If so, simply deactivate any you no longer use and then try again to activate the new install.
