Adobe edition digitale

Hi, downloaded ADE (windows 10), got a link to read a digital book. 

croibien.alain@gmail.com | Adobe ID (urn:uuid:ada911e5-bc16-4278-b22d-86e4e8cd3d0c)

autorisation; worked in the beginning, but by trying to connect in order to read on my iphone, I got a new link. This time it worked in the beginning, but, again, autorisation was needed, and an error message and am no more authorhized. 
It seems that, on top of it, I already got an ID adobe and that it interfers...

Any help?

Thanx, Billsaxo Belgium
