Woohoo!
Ok. Here's the story. We plugged the RoboRIO into the power. Added the UBS B to USB A cable. Connected to the webdashboard. Clicked update firmware. Then the connection was interrupted.
The RoboRIO started doing 2 flashes. This means to reimage[1] it. We've done it twice.
Now the webdashbord is not even loading in.
We're kind of screwed. Any ideas would be VERY appreciative!

Update: Fixed. It was Microsoft Silverlight being a $@#$@#$@#$@#$@#. Needed to switch into IE.
