Im gonna guess that the screws holding it together are self tappers (plastic thread). You need to switch them to the fine thread, also known as MACHINE thread screws. Take all 4 out, and insert a toothpick, or anything really. Just to find out the depth of the hole. Use the longest machine thread screw you can.
