Kinect crashes

Hi All,

Whenever I try to use skeleton node of OpenNi, kinect crashes and I got the below error. The kinect depth node is working normally when skeleton is not used.
I googled it up and found that it can might be caused because of memory issues or perhaps because of 32bit system. I have 8GB memory (4gb extra is hacked) Any ideas?

The drivers are up to date, I tried with several versions. I also tried with Unity program and the same issue arised, Kinect works, but crashes when skeleton is used.

Cheers, Andras
