Can't Activate My PDF Architect Pro

I recently renewed my PDF Architect Pro account. When I try to use the program, it asks me to activate the account. When I try to do this, it takes me to the screen to purchase/renew my account. Is there something I've missed, or wasn't sent when I renewed? Don't understand why I'm having this problem.

Thanks.

Hi Bob,

are you able to login (using the same email used during the purchase) and get info on the currently activated products as described in https://support.pdfarchitect.org/hc/en-us/articles/360022312432-How-to-switch-the-active-product-for-PDF-Architect-on-my-device ?
If this doesn't help, you can also contact support directly through the "Chat now" button on the linked site (might need to ask to talk to an actual person, if AI responses don't help).

Best regards

Robin
