Unusable after latest update.

I tried to read a new book but the app wouldnt sync. It ends up that Amazon updated the app, and all old versions stopped working. Of course I cant update because the latest OSX the kindle reading app now supports is 10.8. All polycarbonate macs are now unable to use the Kindle app. If they had left the old version working, then this wouldnt be an issue. Way to alienate your users, Amazon.
