Are you sure you removed all screws? There are sets of them on the left and right sides (in vertical orientation) and left, right and back sides of the base (horizontal). There’s also the ones on the monitor frame. Mine came apart super easily with no effort after removing all screws, so just making sure you found all of them.The part at the bottom about separating the base parts is where we got stuck. They are rusted to shit and simply refuse to move, truly frozen. I'm nervous about cutting them because I don't want to damage the machine. But I am giving it another try this weekend with better rust remover.
