I bought Affinity Designer after using the trial version.
I uninstalled the Trial version, re-booted then installed the purchased version after downloading it from my account page of Affinity Serif download page.
I launched Affinity Designer but never did it ask me for the Serial Key and email address that I used to purchase it.
I opened Reg-Edit in Windows 10 and went to : \HKEY_LOCAL_MACHINE\SOFTWARE\Serif\Affinity\Designer\1
It shows here that I am using the Trial version of Affinity Designer and not the purchased version.
Under 'Help - About' section in the Menu of Affinity Designer I see no 'Registered to...' or my License Key.
Within Affinity Designer I see no option anywhere to enter the purchased license key, so how am I supposed to use the purchased product with the License Key?
