I have my favorite songs on OneDrive. I just formatted my computer, so the files were not local. In order to get them "downloaded" onto my PC and imported into MM5 library, I highlighted them all, and right-clicked to "Play with MediaMonkey". A song would begin to play, and then ...

The song is over 5 mins, so definitely not too short. I went through that help file, and none of that seems to apply. It's just not being brought in, and says the import into library fails in the log.
So ill open up a ticket.
