1000SRT tempo fader not working in Serato

Everything was working fine, I was DJing for a bit and left for 5 mins to come back with the tempo fader not working. Usually when you're using it to match BPM, you can see the main waveform in Serato Expand and Shrink as you move the tempo fader Up/Down. I can see the waveform overview (waveform between channel 1&2) in Serato working but the Main waveform is not. In my case its not working on Laptop #1 my main laptop. When I plug the controller into Laptop #2 my spare laptop the tempo fader works and you can see the main waveform expand and shrink in Serato. I'm also using the streaming service TIDAL to DJ. Anyone else have this problem? Any ideas?
