Get in touch with beatport. They’ll get the music back that you bought from them, and let you re-download it. One of the reasons I really like beatport honestly, it’s a “last line” defense as far as music backup is concerned.

but… i ended up playing 4 hours and recovered enough to play the whole time including mash ups and quick mix later in the night.
