DJ pro 2 buffering and jumping windows 10

I purchased the full version of DJ pro2 just yesterday after using the free demo for a few days. The demo work flawlessly so I thought great, this is just what I’m after. When I installed the full version all seemed well for the first few hours, now I’m getting glitching and buffering on virtually every track I play. It’s basically become unusable.
Is there anything I can do to fix this?
It’s extremely frustrating to say the the very least!
