Samuel,

I think you're missing several sentences in the walkthrough.

You should see these:
Third clue: The clue on Max' picture states - Poor guy he should see a doctor.
Exit the room and go pass the stairs. Try to open sick bay, the last door on the right.
Look through the window.
Use the picture of Max on the window and meet Oskar, the perpetrator of the paper trail. Nina's suitcase is beside Oskar.

The window that is to be used is the window on the door of the sick bay - the last door on the right.

dear MaG,i am very sorry,i used the spcebar,on my keypad if there would be a window,it would show it,besides this,if i only put the mouse,on a door it will say so,on a window it will say so,there is NO WINDOW on this door at all,its just a door thats it.

Okay. I hope you did check the sick bay.

Here is from Bernard's walkthrough :
Go back in front of Nina's cabin. At the end of the hallway there's a door with light shining beneath it. Use the photo of Max on the door. Nina meets Oscar, it was all just a prank!. Back to the cabin, there are people speaking in there. Ouch, the door hits her head and later she wakes up in the infirmary. Hey, someone is telling lies! Nina has a word with the captain and Mrs. Jordan.
