I purchased and activated this software in 2019 before using for a couple of years and then no longer required it. I now need to use it again and I have re-installed the software from the My Products page however each time I open the app, it shows up with my serial code and email address and when I click Activate & Register Immediately Online, I get the error code -24 and this serial number has already been registered to another email address. I am unable to log in and cannot find a way to do so without the need to activate the serial number again.
