Itunes Won't Play Music

I have updated the Windows Store version of the app, I have updated it there. I have downloaded itunes from the Apple website. REGARDLESS of either version, when I play songs they DON'T even START, and just skip to the next song, to not start, and skip, ENDLESSLY. I am going through a lot right now and not being able to listen to the music that I pay for every month is going to put my mental health in a dangerous place. Why isn't my music playing? I have de-authorized, re-authorized, and restarted my computer multiple times for both versions of this program. Does anyone have any idea of what I can do?
