DDj Ergo V + Traktor pro 2.0.x

Hello.
I've just bought ddj ergo. Used one but perfectly workong. And i want it to use with Traktor pro 2.0.x due to my windows laptop is slow enough and newer versions of traktor make it overloaded.
I can choose Ergo master and phone outputs, but it makes no sound. And also new TSI file doesn't work with such an old version of traktor. Any help really appreciated
