Issues with Auslogics software

I purchased BoostSpeed PRO on 5 Jul (ord#

) for $29.95 as I was an existing BoostSpeed 10 customer. I cannot get the PRO version to activate. If I go to the Auslogics store and enter the new key that was provided with my purchase, I am told that I may either use the FREE version or purchase the PRO version for $59.95! I have already done this with my status as a current customer, which entitled me to the 50% discount. Why can't I get PRO to activate? There are features that won't work without the PRO version! I have a DELL XPS 8930 x64 computer with Windows 10 version 1903 installed.
