cRio not working properly HELP!!

[chriz4gx]

So yesterday my team tested our robot and everything was working fine,wireless,labview,and etc. Today, when we came in we made a tank drive labview code and tried to deployed it(we did "build" and "run as startup"). But everytime its in the "Run as Startup" menu we get an error saying that it failed to connect to real time target. We checked over and over and cRio was definitely powered. We tried changing ethernet cables, even labtops but nothing. We then pinged the cRio at 10.28.71.2 which should be its IP address but once again nothing the request timed out. We have no idea what to do. We tried re imaging the Crio but everytime we click apply we get a box saying that the IP of the cRio is unreachable, to make sure that the computer's network adapter has the same subnet mask as everything else. Also, we tried using NI MAX and we recieve an error. The wierd thing is that we can still use the robot like wirelessly with the driver station and drive it. Please help us we are literally clueless, any help will be greatly appreciated.Thxs
