How are you trying to push or pull the block?
You must get as clos to it as you can then hold Ctrl and press the up or down arrow depending on whether you wish to push or pull.
It Should go in the treasure room, to activate the lift you must have all the tablet in the slots and have Sophia's part in the machine as well as the gold Marduk statue.
