That trace file is very small. Usually the file goes on and on, often repeating steps as the sim tries to load everthing. I agree with the assemenent others have stated. The issue is graphic shader related as the file stops when the sim is unable to keep loading past the shader entries. Your wrapper program may be dx11 capable, but it may not use the PBL style shaders that rF2 converted to after making the change to dx11.
