Engine DJ doesn't transfer to Virtual DJ

Please fix this. I bought this subscription to transfer over to virtual dj and nothing works properly. Playlists are missing, tracks are red. I am using Engine 4.01. You have ruined this app, doesn’t work anymore. I want my money back.

Your app is literally BROKEN.

The fact that you don’t allow people to revert back to previous versions of your shit app is horrible. This new update doesn’t work with virtual dj from engine. Nothing transfers, nothing is there. Broken.

Tried with Engine 4.01, Engine 4.0 and now Engine 3.4. Nothing works.

Can you clarify with what is broken exactly? Really need more info…
