I had this message come up when loading djay for a gig last month, I had to find wi-fi in the building and download a new version (djpro) that cost me £40, which I used for my gig and got refunded by iTunes the next day. Now I can't use that either. Anyone else had this problem?
our apologies, this problem came up because of an Apple App Store certification problem. But after deleting and downloading your djay version of the App Store this should be fixed. Is it possible that you purchased your first jay Pro version at our website?
Had the same issue. Took me a week for Apple to send a new copy of the app. Apple could not find a record of my DJ Pro purchase 6 months ago. However it was listed in my iTunes purchases.... Apple was never able to locate it in "their" system... Anyways good now.
