Reply to Crossfader Bug!

Hey,

When i was using my S4 for about 20mins, then changed the song through the crossfader from left to right. Something must of happened. It automatically heading back to little over centre(the crossfader, i could see on the program) so i wiggled the crossfader on my board to the right it happened again. So i stopped the music.

Whenever the crossfader is on the left it is alright, yet when it is on the right it moves back to little over centre.

I have tried to recalibrate, but nothing changes. Restarted program+ Computer but nothing!!!!

Please help ASAP need it working tomorrow.

Here's a video.
