DDJ SX2 Traktor Mapping - Cant Get FX to work

I have tried various TSI files for SX2 for Traktor and different versions of Traktor from 2.6.2 through to TP3. I can get the jog wheels and loops to work but cant get any of the effects to work.

FX Pads, FX Knobs or Sampler pads.

I have tried to map say FX Pad 1 to Flanger effect but dont know how I would do this and I dont know where I find the Flanger effect.

So either am I missing something when I am installing the TSI file (I followed Pioneers instructions) or is there another TSI file someone can give me please.

This is driving me nuts

Thanks
