Penumbra: Black Plague crashes when loading a certain area.

[TheWolvesofShadows]

In order to help we need the file HPL.log from the Penumbra folder at Documents and detailed system specs, especially when it comes to the graphics card.

This is what graphics card I have: AMD M880G with ATI Mobility Radeon HD 4250
Here it is the hpl.log:
