Hi : glad this forum is here! I just downloaded a Kindle book from Amazon. It reads okay on the Kindle app on my laptop, but can't be read by Calibre. If I try to do so, a message appears asking me "How do you want to open this file?" Beneath this is "Look for an app in the Microsoft Store." Lastly comes, "Always use this app [unspecified] to open .kfx-zip files." My other books all seem to open perfectly. Any help would be much appreciated. Thanks in advance.
