Hello,

well this not copy protection stuff in any way.
More like d3d/whatever bug...
You can also use +snoop to provide better diag because that logs.dll exports
lots of helper functions for the game engine, giving some insight.

--- snip ---

The crash location looks more like an internal helper which does some
transformation/floating point operations on 3D vectors.
At least one of the arguments (pointer to object instance) is 0, hence the
crash.
Could be anything ...
