Good afternoon. I bought Adobe Photoshop in 2008, installed and activated it. I am completely satisfied with it. Email address (activation) is long gone. The old ISP just stopped working. Now decided to move Photoshop to a new computer. I can't log into Adobe ID because I can't change my old email address to the new one. How can I deactivate Photoshop on the old computer and activate it on the new computer? Are there any options?
