penumbra.bin - Permission denied!?

Okay, some time has passed now and still nobody came up with a solution to the problem.
I'm not sure why the Linux version doesn't recieve the same amount of support as the Windows version.
It may be because you don't recieve as much money from it, though, since you sell it through your online shop, you get much more money per copy.
The game is totally unplayable for me in this state. It hangs nearly every time when I try to access the menu while playing the game and doesn't make it possible for me to quit it without a reboot.

The graphical glitches make objects appear and disappear at will and depending on the angle. It's not only ugly, but makes you miss many objects and thus unplayable.
If you're not able to help me with the problem (like with a patch) then I would like to request a refund.
