This error is commonly encountered when the wrong ROM has been selected for the register. (Example: Samsung 1.72 instead of Samsung 1.76.) To fix this, recreate the machine with the correct ROM version, then save all programs from the register. (For information on checking the ROM version, please see the register appendices at the end of the manual.) Note: Some of the files will still save even though the ROM is incorrect. The easiest way to check is to do a Save All Programs.
