Problem with black plague

[Narco2]

hi all,
2 days ago I bought Penumbra Black Plague Gold Edition on steam that includes Penumbra Black Plague and Penumbra Requiem. I downloaded both the games... Requiem is ok but when I try to start black plague a steam window appears saying:

"The game is not available now, please try later"

I waited 2 entire days.. isn't enough?
I Re-installed black plague again but the problem is always there.. I also restarted pc and steam but nothing...

Any solution?PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE[/u]

All are welcome
Thanks.
