Trouble with double authorizations

Hello,

Following an error in trying to copy a book I just had purchased on IBS.it from my Adobe Digital Edition on my PC to my KOBO, I was advised by IBS.it (that where really helpfull and caring) to reset my password/change my authorization. Now I notice that almost all of the books I purchased are gone from Adobe Digital Edition... And I never could download that bloody book I bought and for what I changed my authorization anyway (very frustrating...). I know I have 2 authorizations: one on Marie-Luce.Lovinfosse@Telenet.be (the one I wanted to keep) and one on Marie.Luce.Lovinfosse@gmail.com (the one the support of IBS.it advised me to create).

In addition to that, I have 2 KOBO's : an old one (in my purse) and a new one (in my bed) : I would like to have everything synchronized : my Adobe Digital Edition on my PC and my 2 KOBO's.

Could you help me ? Pay attention : I am really bad at IT matters 😄
