Trying to convert books off my kiddle fire books in prc format using calibre . I have installed the plugins and gone into the plugins to install my serial no which starts with a "D" not a "9" or B" like most kindles and then tried to convert my files.
I get a error error after .01 sec no keys found in o keys tried . read the FAQ at ALfs web site apprenticealf.wordpress.com , but I could not find an answer.
I used calibri using a normal kindle and typed in the kindle serial nu and it converted aze files fine
Any advice or answers
