I have just replaced my old trusty Kindle Keyboard with a new Paperwhite (old one died!) but some of my "docs" won't download. If I try to download from my home page they just remain "queued" or flash downloading for a fraction of a second. If I try to "send" them from my Amazon Account they say they have been delivered but still never appear on my device.
If I look at my device online & check the content then they appear to be on my new Kindle but if they are then I cannot find them on the Kindle itself!!
