I just updated today, made some changes to playlist. But the software will not shut down. Got a spinning wheel for about 2 hrs now. When Quit again it says it is still performing tasks.
Mine did the same thing. If you are going from a Collection that was the old Engine Prime Software it will need to re configure the whole library for the new Engine DJ 2.0. After its done this it should all work as normal.
Hope that helps
