I've also run into this message on occasion when assigning the IP when the PC is not on the same subnet as the cRIOs current address (only on certain PCs and/or cRIOs for some reason)

You may be able to get things going by giving your PC an address on the 169.254.84 subnet and starting the formatting process, it will almost certainly fail but may be able to set the IP to the new IP before it does. If it succeeds in changing the IP you can move your PC to the new subnet 10.TE.AM where TEAM is your 4 digit team number, then try formatting again.
