You urgently need to update the software for your Numark Mixstreme Pro Go. The software has started to freeze constantly. And when the device starts up, it just stays stuck on the Engine DJ logo. The device does not come to the main menu at all.
Try using a laptop to go back to a previous version until this is resolved. I have had issues with mine in the pass with jog wheels and freezing and working with them to get that issue resolved took over two months. Hope you get this issue resolved soon.
