Why won't my VI save correctly?

[danmart]

I created a VI using the DAQ solutions wizard. I then made some modifications to it i.e. adding a filter and graph. I then saved it. Now, after I to open it up and try to run the VI it tells me that I have an error at AI Group Config and that the specified device is not a National Instruments device or has not been configured using the NI-DAQ software. I have set it up using the NI-DAQ software and channel wizard. How can I get my saved VI to work?

Just a wild guess, but maybe there are some controls where you need to set the current values as defaults before saving the VI, else they'll get the plain defaults once you reopen the VI again.

("menu:Operate..Make current values default")

Make sure that "Device" and "Channel" names match the hardware. You can check the device name in MAX (Measurement and Automation Explorer).

The common reason for your error is that the "Device" and "Channel" name controls have been reset to the default values that doesn't match your setup.
