SimpleOpenNI output issue. Only outputs last frame.

I have narrowed my problem down to the fact that it only outputs the very last frame. All the outputted files are exactly the same. I have spent days trying to find the problem, but I can't seem to fix it...
I'm on a tight deadline here and all help will be appreciated :)
The code looks like the following:
