problem with mapping DDJFLX4 with traktor

So before 2 weeks, everything was ok, until I played in a bar. After that when I wanted to connect the deck just with my computer at home, some of the features worked, but others didn't. For example the CFX fader works, but the low, mid and high don't. Also the master level, the trim and the slider below don't react at all. All the effects, hot ques, etc. work though. I've tried every single setting trying to cope with this problem but nothing seem to work. I've googled it but apparently there is no one with the same problem as me. Any suggestions?
