Transferring files to new HDD unable to authorise

Hi there, 

I bought a new SSD and installed W10 on that along with Adobe Digital editions. I tried to transfer my library of ebooks to my new Digital Editions folder but it gave me some errors regarding authorisation. 

I redownloaded all ASCM files from the original vendors but these also gave me errors regarding earlier authorisation.

Now I recall I authorised all of them anonymously (though that was ages ago) so I tried to remove that anonymous authorisation from my old disk but without much luck. I had already deleted the digital editions programma on that disk along with most other programs. 

Next I tried to mess with the registry in hopes that it would somehow de-authorise the anonymous authorisation on my old disk but to no avail. I contacted the original vendor and they informed me they are unable to provide a new acitivation code without buying it again. 

So here I am feeling like I just lost my entire library because I moved the bookshelf two inches. Is there any way to fix this situation?
