NI USB 8452 unload a script

Hello

I have a NI USB 8452 and I need to run several different scripts on a while loop until the user presses the stop button for the loop.

I load the first script and run it, then I load the second script and run it and so on.....

After a while I got the next error:

Error -301703 occurred at NI-845x I2C Script Read.vi:2640001

Possible reason(s):

NI-845x: The number of reads contained in your script exceeds the maximum number of scripts this version of the driver supports. Break your script into multiple smaller scripts.

How can I unload the first script in order to load the second script, and so on?

If we open and close the connection to the NI USB 8452 every time we run a different script works but slows down the measurement system.

Any comment is really appreciated.

Thanks
