Amazon Prime, no previews, videos won't play

Hi,
after a long year of waiting my PPM finally arrived. Looks and works nice so far (Netflix, Youtube, Ted, …) Unfortunately, Amazon Prime does not work. I can sign in and it shows me the menu, names of movies etc. However, it does not load any previews, trailers, videos or anything. Upon clicking the thumbnail, the circle rotates either blue for a short while and I’ll get kicked back to the menu or for a minute or so in yellow and then I am getting an error message “App error - There was a problem during start-up of the app. Please try restarting the app or try again later”. Obviously, I tried rebooting the system without any difference.

I searched the forum and apparently this problem was solved with firmware 1.1.01.

My PPM runs on 1.1.04 with AmazonPrime on 3.0.269.106747

Anybody experiences the same or did before and can point me to a solution?
Thanks!

Download the Android TV version from Aptoide. Should work fine.
