djay pro nor working with vestax spin

I recently downloaded Djay Pro, upgrading from the previous version. I use a Vestax Spin controller as before. When I plug it in it doesn’t always configure properly with the software. Sometimes the output doesn’t connect, sometimes the headphones aren’t configured properly. When these problems occur I go into preferences and correct the situation. Sometimes this works, sometimes it doesn’t. When it is working, if I leave it for a while and go back to it, it is no longer configured properly and I have to reset via preferences again. I do this because I use a mixture of vinyl and laptop when I’m working. I am a professional DJ and I need the equipment top be 100% reliable and it isn’t. What can I do?
