Unable to Activate my PTC Mathcad Prime 8.0.0.0

[MA_10473035]

I am unable to acquire the necessary license to run the PTC Mathcad Express (I want to try the full PTC Mathcad functionality for 30 days). Every time I attempt to activate my PTC Mathcad Prime 8.0.0.0 I run into the following error in the "Acquire License" tab: "You have reached the maximum number of license requests available for your product type."

Furthermore, within the PTC Mathcad options tab, I get the following message:

"2/15/2023 4:32:00 PM : The license request failed.
Requesting MathcadPrime ...
C:\ProgramData\PTC\Mathcad Prime\license\MathcadLicense.dat: (-10) Feature has expired."

Any help debugging this problem would be much appreciated as I would like to do my free 30 trial error before deciding whether or not to update my account to Mathcad Prime 8.

Thank you!

Try to request for a license manually by providing your Mathcad product code and physical address of Ethernet adapter using the following web case logger: http://support.ptc.com/support/mathcad_supportCenterSingleUser.htm The license file will be sent via E-mail.
