Hi there,

Sorry to hear that! What was MIXO doing prior to this? Did you do a large import?

If it continues, I recommend the following:

1. Quit MIXO and delete the MIXO folder in ~/Users/[your user]/Library/Application Support/ /
2. Uninstall MIXO and re-download from the website.
3. Install and login.

This will resolve any strange issues, although you will have to start over with a fresh library.

If you are able to export before it crashes, I would export DJXML or Rekordbox XML so you have a backup.

Let me know how you get on!
