"Djay pro is damaged and can't be opened"

This is the message I am getting when I try to open my Day pro. It is asking me to download the programme again from iTunes, but I don’t want to have to pay again.

What should I do?

Hey there,

as Joe said, was redownloading djay Pro solving the issue?

Cheers,Lukas E.

You shouldn’t have to pay again as long as you are logged into the App Store with the same account that you originally purchased with. The App Store should give you the option to reinstall the app once it recognizes you’ve already purchased it. If it looks like it’s going to make you purchase it, it could just be that you’re not logged into the App Store, or logged in under a different account.
