the penumbra collection won't launch

[gosthrider]

Hi there!

I played overture, now I'm trying to finish black plague. The game was running fine until today: It doesn't launch anymore!

I tried overture and requiem, same problem. Launching them trough the terminal is not more succesfull as the terminal suddenly close as fast as it open...

I tried to install the whole collection again, but no luck the problem is the same. I really don't know what happended and what should I do to correct it!

Please I'm completly mad about that game, hope I can finish it!
