please can you help? I'm desperate, frustrated and disappointed by jellyfin

[Dex Luther]

thank you for your replies. I am happy to see that forum users seem more down to earth than the "official" culture. I am not a programmer, I'm a mere user, and was pointed to jellyfin as such. I'm sure it's huge fun to go through all of the tech if that is your joy. Mine is cinema, not tech.
I have all films on a usb ssd on windows 10. when I go offline, JF keeps spinning as if to load, but never does, even though all data are there. when I use the media player, it refuses to connect.
I can't find any of the options or settings I asked about, and the "official" help is either no help or just wrong (starting with the windows installer itself being for either AMD or ARM processors - NOT intel, and both thus refuse to run).
I don't see my version number anywhere. I assume it to be current, 10.9.10, since I only installed it a week ago.
Below is 
- my movie folder (win explorer) 
- what JF makes of it (homepage)
- a library screenshot. see how many posters are missing and a subtitled film appears twice

Your Jellyfin is spinning (first time scans can take a LONG time especially if you have a lot of files. I assume because it's scanning your files. The homepage looks normal.

Your library screenshot with "Freedom" appearing twice it's probably due to having two versions/copies of that file. It's hard to tell since your explorer screenshot shows the top of your files, but the doubled "Freedom" would be down in the F's. It could also be that Jellyfin just simply misidentified something (it happens no one/nothing's ever perfect). You can right click on each of the doubled items and click on "Media Info"



At the top of the box you'll see "path"



Comparing the path of your doubled item(s) might give you a clue to figure out what's going on.

If one of them was simply wrongly identified, then just right click on the wrong one and click "Identify". Put in the correct name, and year and any of the other information if you have it. You might also want to go into the library settings and turn on other metadata sources (if you haven't already). Not all sources have information on everything (Especially if it's kind of an obscure movie).

If you have the file in there twice for some reason, then you can just delete one (or move it somewhere else).

Also, are all the files in that folder movies or did you mix Movies and TV series or something? Jellyfin CAN mix, but generally I like to keep shows and movies separate (same with home movies and such).
