Well, yes, I think the file should be in the correct place because I followed the instructions in tinyapps page
http://tinyapps.org/docs/e-ink-monitor.html
OS X Mavericks
kindle dxi
Software version 2.5.6
I copied the entire folder kindlevncviewer in the USB storage root of the kindle
The problem now is that the kindle doesn't appear any more when I plug it with the USB cable, and the battery always displays the lightning (charging) even if it isn't connected to anything.
Thanks
