I can't open my ASCM books after redownloading ADE

Hello,

I don't know if there is already a similar issue on the forum.

I've tried to find a solution but I can't, and I begin to feel desperate about it...

So basically, I redownloaded ADE because I had erased it by accident. 

Then, when I wanted to open my books (ASCM, protected by DRM), it tells me to type my Adobe ID. That I did, and that is where my nightmare began.

It popped up a message telling me "The specified account isn't linked to the file you're trying to open" (that might not be the exact message, the software is in French, as I am... French.)

So here I am, a dozen of books I can't open because apparently I'm not using the right ID. And I swear I am.

Hope you have a solution to my problem, thanks.
