I am not sure if this is device related, but i have watched the demo on the calibre website, also gone through the FAQ on the site.
Here is the problem.
The user interface on my Calibre (yes, downloaded from the Calibre website just today) looks different to that on both the FAQ and the Demo. In itself, not a big deal, but the change has left me lost when it comes to connecting with my device.
The FAQ keeps telling me to go to - Preferences->Plugins->Device Interface
But the only options under Preferences are -
a. Change calibre behaviour
b. Run welcome wizard
c. Get Plugins
d. Restart in debug mode

I am trying to get into the device as my UI does not have the DEVICE option.
Also I cant seem to send any books to my device.

Can anyone help? I am tearing my hairs out!
