Traktor Kontrol S2 I/O error

Ok so I have my traktor Kontrol S2 running in Traktor Pro 2.6 and It worked just fine a few months ago but i havent been mixing much lately and now within the last two or three times ive tried to mix, Traktor wont read the soundcard, I can still control everything in the software with the S2 but it doesnt read the soundcard so I cant play tracks. I updated the drivers too, so yeah idk why, but ill try turning it on and off, opening and closing the software and then it worked in left but not right and then a few minutes later worked fully. So yeah idk what the hell is going on. Please help.
