Hello all,
I am having Mathematica (trial version) - it will expire on June 26, 2020. I am willing to buy (Mathematica Home Edition = £229.00)
When I fill my card information, and click "Process my order", a message appear: "Payment was not confirmed"
Is that because the trial version is still valid? Must I pay after expiry?
Or is it because a technical problem? 
Thanks!
