This typically means that the instrument software was upgraded at the factory, and the ASIV @ Work application has detected a different version.  The solution is to delete this instrument and add it back so the software will recognize the instrument.   This can be done in the configuration menu, accessible by clicking "Configure" from the main menu. Another reason you might get this message is if a different instrument than the one you are using has been selected in the Configure portion of the program (Instrument tab).
