I have just installed this plugin. Previous I've used Kindle for PC 1.17 to convert books, but wanted to purchase a newer book so installed this plugin. I also installed Kindle for PC 2.3.5 (70840) and have latest calibre update.
Have been using Tools 10.0.9 since last fall without problem on pre 2023 books.
Something is not working for me. Posted below is a book I tried to import into Calibre. It is a past purchased book that previously was imported without problem as aw3, now it is KFX.
Spoiler:
"calibre, version 7.11.0

I'm not sure if this can be addressed here or not, but thank you for your time if you can help.
