rekordbox license bug OS X El Capitan (10.11.1)

After updating to OS X El Capitan, rekordbox DJ license has been removed from my software and is now stating it is already being used with another computer. Upon restoring my macbook back to a date when the license was working, and previous OS X version, I am still having the same issue.
