My game, after loading in has 5 spotless minutes of game play, then freezes in two short bursts then just, dies. PLEASE HELP I LOVE THIS GAME.

I have played 3 and 4 and enjoyed them both but I am struggling to figure out how to pull stuff in the demo

I just bought the game and whenever I boot it up it shows a white screen for a second then crashes. I tried verifying the integrity of the game files and even reinstalling it and nothing works! My specs are way above the minimum requirements so I have no idea of what's going wrong. If you know any way to help please comment, I know this is a really good game so I'd rather not have to refund it....

There was a plugin for them to work on blender but it has been deleted. Is there any ways to import/convert .rbm models?

right...?
