FATAL ERROR at the start of launch

[KamWhaBam]

So the problem here is that I wanted to clean up my game so I uninstalled then reinstalled the whole game on file, (I Use the redist/ folder version), and I came back after encountering multiple problems like missing dll's, audio problems, graphic card problems, and computer repairing: And what I see when I immediately start up my game; FATAL ERROR: Cannot load vertex buffer from mesh 'Core box.dae'. I have looked up multiple articles for solving this, however my specs and computer does not match up to theirs. I have litteraly been dealing with this on my own for 1 month now. Am I missing files?

Computer props - Windows 7, NVIDIA GEFORCE 250, and Amnesia type: Redist.
