OBOK Doesn't convert Kobo eBook

[another4til7]

Question / bug report

When I tried importing my first book with oBok, it thinks it succeeds but when I open the file I have giberish:

$���r�7�O�ϝ��3\�LP}���i�b���L�D�w����u[��5�U�t�ؐ=P��S�xe��W��2��~�� X55��I��l_,��i���Y�$�

FWIW, the book is a brand-new release (yesterday?)

Which version of Calibre are you running?

Which version of the DeDRM plugin are you running?

Give Obok 10.0.9 a try. Also close Kobo Desktop before using Obok. Obok should show a red closed lock on books with DRM.

@ElleKayEm wow. That was easy. Thanks for being the key part of the howto article no one seems to have written.
