Have you got the problem that no cdkey displayed in Amazon game library?

"For those of you having problems viewing keys, it is just a function of the system getting hammered a bit (lay off the sauce system!), it should resolve itself within an hour or so."

It is a huge pain if you buy a number of games, like the big Paradox pack, and have to separately click each show key, only to have the keys disappear after the first click. Could make a sane man lose it. I don't know who designed the system, but not having the keys cached on the main servers, for the client, is ridiculous. It has to request them from a separate server, every time, as far as I can tell.

If you get through to your key page once, quickly open the same page once for every single key you need to activate. The server connection should be maintained just long enough for to get all those pages open. I would just middle click in the address bar, if your browser supports it. You may have to delete a character, then readd it to get the option to go to the site. I had to do that in Firefox. After you get that option (It's a little arrow pointing to the right in the Firefox address bar), use it to open the same address over and over in new tabs. Then you can activate show on all of your keys. Likely, by the time you get to the end the connection will be lost, but the show key command will still go through. So then you activate the show key for all of your games at once and just have to sit around refreshing until you get back in, only once more. Better than doing it over and over. Not to mention that it is better on the server because you won't be up all night hammering it. One small hit is better than a whole night of them. Most of it is probably in your browser cache, anyway.

That is what I did and I managed to get all of my keys to show fairly quickly.
