UPDATE. We got ours working by trying a different laptop. As others have suggested here, it looks like the the first laptop we used was losing connectivity with the cRIO during the formating process. The cRIO was working fine, the laptop could just no longer see it.

If your still having issues, try the suggestions posted in this thread:
Make sure Firewalls are off.
Wireless is off.
Only one ethernet adapter is enabled.
Check IP settings.
