Hi,
I just got my Kindle Paperwhite 2015 yesterday and so sad, it seems like my Kindle cannot recognize anything, except for some books that have already been on my Cloud.
I transferred the file through usb cable but even though they are on the document folder, they don't show on Kindle. I also tried to send file via email and synced many times but nothing appears
I haven't tried other app like "send to my kindle" or Calibre because I'm using my company's laptop and it doesn't let me install anything.
I don't know what went wrong

This is my first Kindle so I really have no idea
Have anyone encountered the same problem? Please help me, thank you very much.
