Problem using kontrol s4 mk1

Hi guys , I have recently switched from Traktor to Djay Pro 2… I have tried mapping my. Traktor s4 mk1 to Djay Pro 2 bit does not work… I have used the mapping on Dj tech tools but still does not work… I know it works with the native supported controller but it is a shame that I have to buy another controller just to use Djay Pro 2… is there anyway I can make my s4 work with Djay Pro 2?
I have used many of the tips on this forum and YouTube , it worked once then stopped working …I can see a lot of DJS on this vetoes are have the same issue with their s4 … Is anyone able to use their kontrol s4 mk1 without any issues ? Please help
