I reinstalled Leadwerks today, now all is on the right place.
Possibly I made anything wrong by creating the first C++ Project.
The example 07 AI and Events.map is now working too, in the first installation
the pistol was not loaded, now it works, the pistol was in the folder but possibly corrupted.
I made a repair check by Steam yesterday but this solves the problem not.
But now it's working all.
