Problems with new analog scales en GE Powelink 3.04 DNP over Factory Link 6.5

From some years to now, a change of engenieering scale over an existing ANALOG TAG is not recognized when I launch Start FActory Link....The sofware was licencied over the 2000s....but something seem to be wrong...may be the time of use...?
I have tried to install in other PCs, but the effect is the's not possible change the Analog TAG Scale to a new value....the Software
keeps unalterable the original Engineer SCALE when the software run in real time...The Real Data Base show the original value, example...amps, voltage, power, etc..

Thanks a lot for an advice...and sorry my basic argentine enginner grammar...

Best regards.
