Downloaded ADE while logged in, but now seems like my book is linked to "unknown" user, and not my user...

Like asked in the headline.. I am new to ADE, and cannot figure out how to login in the program? I just downloaded a book, in the belief that I was logged in, because I was logged in to adobes webpage when dowloading ADE. It didn't pop op to log-in while downloading the book. In the guide in ADE it says that the login option will come op when downloading a book... So I assumed it was because I was already logged in. Though it really seems like I'm not. How can I see if I am logged in??

Really hope someone can help me and that I didn't just loose the option to open my book on other devices..

Thanks!
