Adobe Digital Edition link between computers

Hi all,

I try to read a ebook from a laptop that have been dowloaded and authorized from my PC.

I have first dl it on pc, read it, on pc, but i have used no ID connexion because I wanted to do it later.

Then I tried to do the same on laptop, but impossible to reach the authorization. From this I began to log with an ID from an adobe account, on the two machines. Since then, it's impossible to me to read again the ebook, on PC and on laptop.

I had severals errors statement trying these like : ebook used by another utilisator, thing like that

and the two adobe accounts on the computers is the same

What did i do to end up that bad ? if somebody can help or explain the process to read those books u save my day

Thanks, i hope this is a common feature but i haven't saw any answer to this in the forum.
