Driver Station & cRio communication problem.

[Zambie]

Summary of the problem.
Driver station user can't communicate to cRio. Developer user works as expected. Driver station should, I believe, communicate to cRio.
Tried several troubleshooting to solve the problem.
-Installed latest updates for driver station/utilities/labview.
-Developer profile can communicate to robot(transfer files/deploy projects).
-Robot is tethered.
-Set to use lan/ethernet
What we have tried so far.
-Using another cross over cable.
-reimaged cRio several times
-check power
-checked ip.
There's a possibility that cRio might have gone bad.
Going to image the classmate again, setup driver station in a attempt to fix the problem.
