I'm stuck here then. I searched a bit, it appears it means deDRM failed? I then found this page but i'm a bit confused on the process.. I tried loading book in 4.23 with deDRM 6.xx but it shows unknown cover, so i guess failed too? Please confirm and tell me what i can try, thanks!
AZW is just the file extension. It sounds like that's KFX format. Detailed help with DRM removal isn't permitted at MobileRead. I recommend using noDRM's DeDRM v10.0.9 plugin, and asking for help at their github repository.
