If you have used my tool before you should check
Overwrite existing personal documents (PDOC) covers? option at least once.
Note that there is a new option for users with older firmware devices:
Fix book covers for PERSONAL badge?
I redesigned options in a way that for a normal usage you do not have to check any checkboxes
I also changed compilation tool for Windows binaries to Pyinstaller so please reports any problems with the binaries
