I want to read kindle books in kingq

I have tried to import kindle books into lingq but it was not a success.
it shows this error:

:camera:Error:0: 500: Could not download page (415) "

what should I do?
as I am new to use lingq, could anyone tell me how can I solve it?

Have a look at this thread:

Can you send me the link to the thread, too? Or reply and include the link?
