Hi all,

since a couple days every download from Amazon fails for me with an ominous error 909. I already did a couple attempts to get it resolved but as of yet no luck. Streamfab is able to open the AP site and I can navigate to the video I want. It correctly analyzes the video and I can add it to the queue. When I start downloading it seems to work fine until it reaches near 90%. Then it suddenly fails. Happens on every show I tried, the example below was for Big Bang Theory S9E13.

Here is the part from the log wherer the trouble begins (while analyzing):

And then soon after, the terminal error:

– Watching the video from within SF works.
– Downloading from other providers works.

What I already tried:
– Serveral different combinations with other resolutions, audio as eac3 or aac, different or no subtitles
– cleaned the temp folder
– a complete clean install of SF on a fresh and clean Windows installation. No leftovers from old versions, no other software running.
– clean install of older version on a fresh system. The error appears just the same on 6.2.1.2 and 6.2.1.9

Any idea on how to solve the issue would be greatly appreciated!
