hello, i installed my flip top and everything seemed to be okay. But when i tested it for the first time, i pressed the eject button, then placed in my swap magic. The problem was, the tray didn't go fully in. So i took it back apart, with the tray still sticking out. Now when i try it with the cover exposed, the tray will go in a bit, but will be stopped by this central shiny circle object. Below the tray, the bottom that has the shiny circle thing on it moves up and does not allow the tray to go in. Please help, and thanks in advance.
