1. Check to make sure your devices are showing up correctly in NI MAX. If they are not, follow the MXI Device Is Missing or Incorrect in NI-MAX
2. Take all of the PXI/PXIe cards out of the chassis and see if the error occurs.
3. Reintroduce each card one by one and see if the error occurs. The goal is to see if a specific card is causing the error.
4. If you still receive the error contact National Instruments support.
