All options under my Koboereader on Adobe Digital Editions are greyed out and it won't let me unauthorize to do what you suggest?
Any other suggestions?
What OS are you using on your PC? Can your PC see your reader in File Manager, or its equivalent?
Windows 10 is my OS and not sure where to look in file manager? under the Adobe digital Reader it shows my Koboreader, when I plugged in the usb port to my pc
