[anon(8829200)]

What does the 8007045D error mean on my Lumia 920? When I want to play some music or video this appear.

What format are these songs/videos?

What OS version and firmware are you running?

I got this too. Started with a couple of music files this morning, now this evening the ones that worked this morning don't work. All MP3 files.
