Reply to Traktor Pro version 1.2.3/ Vestax100 SE

It might sound easy for you but hopefully somebody can help me. I bought Vestax 100SE last October 2009.
Installed Traktor Pro version 1.2.3 and the midimappin on DJ Techtools (Version 2_5 for Traktor Pro Version 1.2 and above) but somehow the mappin doesn t work. what am I doing wrong.
