Error: Cannot read the Gamefile

[Ramsanx]

When I try to play some specific fangames, like 'conquer the blowgame', this message pops up: "Error: Cannot read Gamefile" (I use Windows 7)
Can anyone tell me, how to fix it or atleast what causes it?

While Im already at it: For most of the fangames I play, it says "Sound device not detected, sounds might not play", when I start one.

Thank you!

If I remember correctly, that error happens when there are unusual characters in the file- or pathname. Renaming them fixes it.

No idea on the sound device error though
