Adobe digital editions error getting licence

[Daniela2017]

Hello, I re-installed Windows and can't activate Digital Adobe editions any longer. The error I'm getting is "E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER" I cannot read any books I bought because of this. Is there anything I could do to prove that it is me who uses Adobe digital? It is the same PC that will see this maintenance carried out 2-3 monthly, Will I have to go through this again next month? Thank you

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Digital Editions forum so that proper help can be offered.
