Missing song titles

[Mikelap]

I Open Musicbee to listen to some music some screen opens about AIFF not supported  didnt make sense so i dismissed it and close window without really knowing what it was so i open an album and i see all the song titles are gone and this happened to the first 180 albums  the rest of them look ok i only have a couple AIFF albums so i dont know whats going on i checked where my music is stored tittles are all there . What can i do to get my titles back . Thanks
