Hey, I will try something else ...
Here a new version (the content did not change). I have just added some code to see where it goes.
So, to view the "log" you have to use the command line to start the program. To open one in the folder where the demo is, press the shift button + right click on this folder and new menu will allow you to open a command line here (funky windows, isn't it)
And then type DBN.exe and it will see the log in the console \ o /
So please, report me.
As a precision:
Not working at my home on Geforce 5100 / TNT2 (I have really old computers)
Working on Geforce 360M
And finally, just to spot the problem faster, the demo needs FBO (Frame Buffer objetcs). If you don't have it (or supported by your driver, the demo will not run (and now, you have a message to tell it :s)
I am really sorry about that.
If some guys able to run it could produce a video capture, I will be really tahnkful (since I don't have the internet connection to upload it ...

)
Thank you very much for your support, sorry about the annoyance.
