Getting the same message about needing to sign in, after I signed in successfully

When I try to open my app Photoshop Elements 12, I get the message “Signing in with Adobe ID and registering Adobe Photoshop Elements 12 is required within 7 days otherwise it will stop working”. So I click on “Sign In Now”,  I enter my email to sign in, I am asked to enter the last 4 digits of my phone. I do that, I get a password on my phone, I use that, I get the message that the sign in was successful and that I can return to my application and when I return to Photoshop elements 12, I get again the same message: Signing in with Adobe ID and registering Adobe Photoshop Elements 12 is required within 7 days otherwise it will stop working.
