Which device do you use? Where can I download the DD files?
Actually, this error happens because of the mismatch between dd file and the device. NI Configurator just follow the FF specifications to do the comparision.
One possible reason is the compatibility. The DD files are stored in \National Instruments\NI-FBUS\Data. Go to the folder of the files you load by Configurator Utility. For example, \National Instruments\NI-FBUS\Data\0007d0\0080. If you see some other files, backup them to another place. Because the DD files may have several versions, the Configurator will load the latest version which may not be compatible with your device.
So, only leave your downloaded files in the folder.
