messhall crash

[NemaN]

First of all sorry about my english, here it goes.
My game crashed in the middle of loading every time i try to enter messhall, i have downloaded and installed the 1.0.1. pacth and it worked.
And this is where the problem starts, now i can enter messhall but i cannot interact with doors, barrel that i need to set on fire is ALREADY burning, the switch does nothing, fuse box is closed and cannot be opened, when i drag the already burning barrel under the sprinkler nothing happens.
I have ati 9200, 512 MB ram latest drivers and it still doesnt work, if u could help me that would be awesome.
here is my hpl document if it helps.
