I ve received this Email from Genjix (thank you man), ok it doesn t work for me but could help other people with the same issue a community is made for this no ??

Try this,
http://www.crystalspace3d.org/downloads/celstart/celstart-v7-win32.zipdownload and extract to some directory. No other installation required.
Set CRYSTAL and CEL to that directory. Set PYTHONPATH again. Now try (but you
have to have celexport checked in blender).
You will need:
1. A plane (the floor), some lights, and a cube somewhere.
2. On the Cube set the property player: true, and the behaviour: actor which
are found in the second tab.
3. On exporting tab, click celexport, and then Run.
