Hi Lourdes,
You can find everything you need here!
Click 'Sign in' at the top-right corner. Enter your Adobe ID credentials. After you're logged in, select your name from the right hand corner to bring up the drop down menu, click on 'My products and services'.
If you registered your software you will find that info here! Also if you belong to any of our online services.
Hope this helped! Let me know! Looking forward to hearing back from you.
Regards, Stacy
