The REX board needs to be seated all the way down. It should feel firmly inserted into the socket, it might not be making good contact all the way round. The REX programmer will run to completion even if the board is not properly inserted.
After running CALL63012 does the machine lock up or return straight to the MENU screen? If if returns to the menu immediately then in general the REX is not being seen, a bad REX will usually cause the MT to lock up when trying to start the REXMGR - if the onboard FLASH is corrupted.
