Can't upgrade Smart board M600 firmware. Serial Mismatch?

[blong]

I'm at a loss with this board. I have upgraded several throughout the school and when I go to update this board I'm greeted with the following. Serial numbers mismatch: Bootloader is EMPTY, application is M06260141 YYYYY with a weird line above the Y's. Also when I open up the hardware settings on the board It has no serial number. I went to another board and didn't have any of these issues. The board is still usable it just looses the orient function every so often and sometimes the pen tray doesn't work.
