Hello,
Thank you for contacting National Instruments.
The easiest thing to do to solve this problem would be to install the latest FieldPoint driver. Installing the latest driver will ensure support for all of your hardware and it will replace your 3.0.1 DLLs with the latest DLLS.
Here is a link to the FieldPoint 4.0.1 driver:

With this new driver, you will interact with your FieldPoint hardware through the Measurement and Automation Explorer. If possible, I recommend that you uninstall your FP 3.0.1 driver before installing 4.0.1.
Please reply to this post if you are still having problems with this issue.
