I was roaming MSI to see if anything new had been added. This just before Sarah leaves to follow the voices. I found another music room to the right of the large music room on the third floor. I think it's new, I hadn't seen that door earlier. And I found another door that I don't think was there before on the second floor middle of the north wall in the upper left section behind the play area and the stairs leading down to the left upper section of the main floor. Again, I don't remember seeing it before. But when I try to open that door, the game crashes with this message.

Is there anything important in that room? My latest download was April 25th.
