CD Djay for mac not updating?

I have an older CD version of djay and it won’t update past 3.1.4, do I have to repurchase it from the app store to get the newest version?

Hi Floyz,

You are entitled to a free upgrade to djay 4 if you purchased djay 3 on or after AUGUST 2011. In this case, please send an email to support@algoriddim and make sure to attach a copy of your purchase receipt (or at least your current license key).
