HELP PLS! Record volume is too low on 2.6.8 (DDJ ERGO connected)??

I upgraded Traktor 2.5 to 2.6.8 and when I am recording internal(ddj ergo has its own sound card) I cant hear anything. Even I increase the gain to maximum level, the green bars, which shows the volume level of the record, are increases so little. I tried to make headroom setting to -13 dB but still not working.

Thanks for answers
