Overture keeps crashing

[MccGarthur]

I keep getting multiple crashes during gameplay; first when opening the hatch in the very beginning with the metal rod, second when first encountering a dog, and watching it walk off screen, and lastly when I tried to open up the door to the workshop.

My specs are:
Windows 7 64-bit
i5-3570k @ 3.4GHz
8GB RAM
NVIDIA GeForce GTX 670

I have attached my hpl.log

After the first crash, I verified cache integrity via Steam, and 42 files couldn't be validated and had to be redownloaded. Second time, 10 files, and the last time it was able to verify 100%.

I was getting exception_access_violation error, but now when it is retrieving the crash data, it gets to 34% then says penumbra.exe has stopped working. I don't know how active these forums are, but any help would be greatly appreciated.
