Anybody use Audible on J3?

[J3fornia]

Hi
I have been having trouble getting my audiobook to work.

I have tried both manually transferring the file to the audible folder in the J3 root folder, and using the Amazon audible manager to transfer the file.

It is confusing because after the transfer, the audiobook is nowhere to be found in my J3.


I was wondering if there is anyone here who has successfully transferred and used audible files on J3.

I don't know whether the audible file should be .aa or .aac
but mine is in .aa format.

Should it be .aa or .aac?
Where do I place this file on J3 root folder?
