I just tried to download one of my Kindle books and it said 'too many devices' - deregister or something...

What's all that about?

I'd apparently exceeded the number of devices I was allowed to download that book to. That one and some others. Maybe 10 or 20 out of the 300 I've got. The majority downloaded no problem.

But I don't actually have any Kindle devices at all.

But I've been using Kindle for PC since 2012.

I found the devices thing and I see I've got Kindle installed on 12 devices and Amazon on 1.

And I've got little or no idea what that actually means. I see the list goes back to 2012.

Looks to me like every time I've had a system disk crash and had to rebuild (relatively frequent, for me, with windows - four in the last couple of years for instance) then when I've installed Kindle again it has recorded a 'new device'.

Is that it? What's the point of that?

And I see that in 'content' the highest device count of any title seems to be 7 and there's only one of those.

And I see no indication anywhere of a 'device limit' mentioned with any title.

I find it all very puzzling and when I can't download (I'm just recovering from yet another system disk gone down) - annoying.

How'm I to understand all this? And deal with it?

p.s. If I want to deregister a device as it says, to enable me to download these volumes, how can I check that the titles listed for that device are still available for me? Or is that a given? Any/all titles listed for any device at all will always be present in your kindle listing?
