Because Dollar Photo Club was purchased by Adobe. However, I can no longer see any of my licenses (purchase history) for the many images that I have purchased from Dollar Photo Club. And, now I can no longer access my Dollar Photo Club account (since signing up for Adobe Stock). Help! (I need to have the information about image licenses from Dollar Photo Club). This affects multiple client which I have.
Please check the FAQ for details - Dollar Photo Club - high quality royalty free stock photos and vectors - Dollar Photo Club
As part of the migration process your DPC account is permanently closed so we don't have an option to retrieve this information I'm afraid.
