Pdf acchitect professional activation issue

I have pdf architect pro and just downloaded update and now when I try and edit a doc. it sends me to your web page to buy it. Help please.

Hi,

did you install a minor update e.g. from PDF Architect 6 to PDF Architect 6.1, or was it a major version update?
Do you have a serial key or a subscription?
If you have a serial key, this is only valid for the main version you originally purchased.
If you have an active subscription you should always have access to the latest version and usually logging out of your PDF Architect account and back in again solves the issue.

Best regards

Robin
