I can't seem to do anything without the part that holds up the art falling off. I can't seem to find any instruction on how to set it up. Not in the box nor on the internet.

I've already physically hurt myself enough opening this box and getting it up, so help at this stage would be appriciated.

Thanks in advance.
Pictures will come when they stop refusing to upload.

EDIT: Whoops, set it up the wrong way. This can be locked.
