Every time i start Creative Could it tells me to verify a email i dont know (firstname.lastname@example.org).
I cant log out or something else!
What to do?
The Email provide in the screen shot is not a Adobe ID,
The email you have used in forum is an Adobe ID, the CC is in trial as there has been purchase.
If you are planning to install the trial then you can use the email in the forum.
To log out of this CC desktop App, follow the instruction in
Open the cloud app and click on the little gear logo, select "Preferences…". In the "General" tab, click on "Accounts", then click on the "Sign Out from Creative Cloud" button. It will then ask you to log in and will act as if your apps need to be reinstalled, but wait a bit and it will recognize what's already installed.
