I am using Kindle Scribe Firmware 5.16.6.1 and Calibre, version 7.5.1 worddumb-v3.31.0.
Worddumb works well with my Kindle Oasis,
But when Kindle scribe is connected to PC, everytime I click 'Customize Kindle Word Wise' button, I see this message:

Word Wise database not found: Can't find Word Wise database on your device, open a Word Wise enabled book to download this file.

But I do have downloaded a word wise enabled book and kll.en.en.klld file is in the kindle kll folder.
Anyway, after I do 'Create word wise', the files are copied to the document folder of the kindle but word wise is not enabled.
I tried KFX and AZW3 format, neither worked.

Some times, I got these :
C:\r\src\src\calibre\devices\mtp\windows\content_e numeration.cpp:710:Cannot write to file:[hr=0x80042009 wCode=7689] IDispatch error #7689

or,

I tried every version of worddumb from worddumb-v3.28.2 to worddumb-v3.31.0
None of them works. What would be the problem?
