They did reply and maybe not so much as "refused to help" as said there is nothing that can be done except for me to upgrade. Was hoping there was some work-around that some clever people thought of.
Hi (Name),
Unfortunately Flickr made some changes to how accounts get authorized, and the way that it was done in Photo Mechanic 6 no longer works. Development on Photo Mechanic 6 ended in June of 2025, and as services that it connected to see updates, certain functions of the application may eventually stop working correctly. The issue is already corrected in the new version of Photo Mechanic, so the solution is going to be to upgrade. To get a discount on upgrading, you can go to the 'Help' menu in Photo Mechanic 6 and click "Choose Upgrade options".
Best regards,
