Hi there, sorry for ressurecting an old thread, but I'm experiencing the same problem. Applied the hotfix install and no KOReader version seems to load for me.
My specs are:
PW3 (7th gen)
FW: 5.16.2.1.1
I did manage to install KUAL and Helper after a few false starts, so I'm suspecting it's an old version that's causing it? I've already try
this too, with no luck.
Either way, attached the crash log, lemme know if there's anything else I'm doing wrong!
