Abduction: Chapter 2 [RELEASE] (Chapter 1 download included)

[Elexyr]

So, I ran into a little problem in

Spoiler below!

East Wing, where I got to the Blue Shard, however, finding no means to move the bookcase infront of the little room.

So, I left it and went for other shards. When I returned, the wall you destroy to get into the room with the movable bookcase, can't be destroyed anymore.
I've tried throwing stuff at it aswell, to no avail.

Oh, and I'd like to know how to get past that bookcase... Kinda tried everything, and I see no "lever" or combination stuff to use.

Thanks
