Vec3 Pool Size

So I downloaded Huzuni earlier and whenever I tried to play, it crashed.
Here is the crash report:

If anyone has any clue about this, I could do with some help. I'm not sure, but a factor could be that my OpenGL is out of date.

 

It's an old PC, has a pretty bad graphics card, not sure if it qould work.

 

I have tried that twice, it hasn't worked, but I'll give it another go.
