cRIO not being found by imaging tool

[DrewG]

I have been trying for two days to reimage the cRIO and our computor still cant find it.
I am using the correct ip address and subnet mask, I have turned off wireless connections, I am using our newest ethernet cable, I have turned off the firewall, and I have the latest update for all FRC NI programs.
I have tried going through the router and directly to the cRIO (both of which still have the correct ip adress as well, as far as I know, though I have forgotten how to check on the router), neither has worked.
Please provide me with anthing you think I may have done wrong, or direct me to another thread if this has already been covered (I coudnt find one)
