installing Brekel Kinect and Motion Builder Plugin
you can download all the driver you need for install the drivers, at http:\\www.brekel.com
the reasons you might have problem and it won't work:
if Open Ni doesn't work, is because you didn't uninstall the "Kinect Audio" Driver, which you can find it under Device manager, and uninstall it.
another reason might be OpenGL, if OpenGL version is older than 1.5, Brekel won't work, so you have to upgrade your graphic card software to latest Version and in case if you graphic card is updated and OpenGL wont go higher than 1.5, then you have to change the graphic card.
