Hokay... Thanks everyone. Here's the scoop. The problem wasn't with the Amazon Downloader. The issue is with the old My Favorite Martian series. Part of that series did not download and errored out. The error changed to 322 after I tried to re-download the series after I was out of downloads for the day. I recently upgraded to a Fiber connection, blew through my entire days allotment in less than a quarter of the time it usually takes, and just didn't notice that I was out of downloads for the day. Thanks to #Stan001, who was the first to notice. What I'm trying to say, is the 322 errors were my own stupid fault. :o
A big chunk of the My Favorite Martian still errors out, but not with the 322 error code. Since it's just that series, I believe the issue is on the Amazon Side. Even though it loaded into StreamFab, I can't find Season 3 on the Prime Video site to see if I can play it outside of StreamFab. Although I got a little upset when the Moderator insinuated that I didn't have a license; he was right to close the thread ...just for the wrong reason.
Note: (An experiment) I loaded a long list in the que, and let it "Cook". When I ran out of downloads for the day, instead of Streamfab just stopping and saying I was out of downloads, It kept going and put a 322 error code next to every file past the download limit. Perhaps I need to post a suggestion that Streamfab stop checking subsequent files when the counter reaches zero, and display a "Download Limit Reached. Please Check Back Tomorrow" popup. The counter should be a checkable variable. :)
Thanks to everyone who responded to this thread, and at least read it to try and help. I appreciate you all - Mystery Solved. -
