why do I keep getting error -65581 when trying to use a cRIO 9024 and c series modules

[NMAYO]

I am simply trying to send out a digital high on DIO0 of a 9401 c series module and I get the following error every time.  

Error -65581 occurred at Shared Variable in Send True Value Out.vi

Possible reason(s):

CompactRIO:  (Hex 0xFFFEFFD3) The FPGA personality currently running on the CompactRIO chassis does not support the RIO Scan Interface in this slot.

This error or warning occurred while writing the following Shared Variable:

\\NRL-CMG-cRIO\NI 9401-1\DIO0

\\170.126.209.52\NI 9401-1\DIO0

Any help would be greatly appreciated.

NMAYO,

In your project view can you right click on the chassis in the cRIO and make sure that it is set for Scan Mode and not FPGA mode? Also, In the measurement and automation explorer you can check the cRIO and verify that it has Scan Engine Support installed on it. The tutorial below shows how to reformat a cRIO and install software on it, the later steps on software will allow you to check your cRIO.
