Sorry i couldn't send you the file cause it contains some personnal info but i found this in it.
d3d11: failed to create vertex buffer of size 116640 [0x887A0005]
d3d11: failed to create index buffer of size 5556 [0x887A0005]
d3d11: attempt to lock null vertex buffer
d3d11: attempt to lock null index buffer
the last two lines repeat almost endlessly in the file so I thought it was the bug. I hope it helps you improve the game and thanks for answering me. (I have a GTX 560 Ti in case it has to do with the graffic card.)
