Another serial number question i'm afraid

Hi Mixvives team,
I purchased the Cross DJ software and the U-Mix Control Pro controller a couple of years ago and over the last couple of weeks I am trying to get it up and running again. My problem is that I have downloaded software version 3.3.11 and I cannot find the CD that had the license key on it. I have version 2.2.0 working on my laptop but it needs some kind of update as the sound output isn't great and there is no output on the headphones.
Originally I did register on this board with a different email address and updated my profile with the license key however now I am unable to log on with my original credentials and therefore unable to retrieve it the key.
Is there anything you can do to help please?
Thanks in advance
