We want to welcome new users who discover Cross DJ for Mac through Apple Appstore.
We can't with the Appstore rules deliver you directly a full Mixvibes licence like we do with other shops.
But if you want to submit it you can.
How to do it:
-Register on the forum with the same mail than on the appstore
-Forward the appstore bill you received to:
djcommunity@mixvibes.comBy return you will receive a full Mixvibes Cross DJ license for Mac & PC and the full support of the forums.
WARNING: This offer is only for Mac users and doesn't concern Cross DJ on iOS for iPad
