Hmmm.... That's strange.
As a diagnostic, I just recently downloaded and ran the program, and it appears to be working fine from my end . I had also received some feedback from users in the past of the same variant who apparently were able to play the game without any issues.
I would note that the model in question applies fixed material settings as specified in Blender, rather than conventional textures. So, it's possible that this configuration may pose compatibility problems with certain system types which I am not aware of.
I don't know. I'll have to look into this. Sorry for the inconvenience.
