From the middle of the game is nothing more!

I had decided for this game because I previously played games this manufacturer and at all had no problems. But this game is no longer goes from the middle, unfortunately, continue! The left bar (where help and zooming) can be seen but everything else remains black, you can indeed rumtippen, but what if nothing happened ?! Annoys me totally, have money paid for it !! Four stars I forgive anyway, because the game was so not so bad ..... until then ...
