I bought pse9 then upgraded to pse10. The years pass...
Ive got a new lease of life with my photography and want to log in to see what goodies I may download and maybe upgrade again. Ooops, the email I used is now defunct and I dont remember a backup. My phone number was also changed a long time ago. This means that when I tried to log in the pin number was sent to a non existent email.
I have my old password and the serial number. I need to activate the old account or change my product to this account which I have just created in order to place this request.
Unless you need the old software version, I suggest you simply use a new Adobe.com account which you have apparently already created. If you still need to access the old account, you are going to have to contact Adobe support.
