We were having the same problem with Crio and we managed to fix the problem.

We used the link above and followed the three steps( after the third step we set the RESET IP switch back to on).
We checked that our IP settings were correct on our laptop. We ran the FRC 2013 Crio imaging tool, and we successfully imaged the Crio.
