Adding music? :/

[Deadly Lycrish]

Whenever I try to add music on a level, I get a critical error, and the editor crashes, is there a way to add BGM?

thanks.

Edit: also, how do you edit the description and the preview image(s)? :/

All the three things are done via View -> Level Properties.
Audio is under Audio. You have to add a filename there, without the extension .ogg.
Description and preview image is under LevelSummary.
