"The chassis has detected an unrecoverable error"

[Namazu]

Our cRIO has a solid orange status light. It worked just fine this morning, but then we re-imaged it in an attempt to fix an unrelated problem. I don't know exactly when the light went solid, but I think it was right after the re-imaging. Either way, it's solid, and our robot won't connect to the driver station, cRIO imaging tool, or Windriver. The manual published by National Instruments for the cRIO FRC II (What we're using) says that a solid status light means that "the chassis has detected an unrecoverable error" and you need to "contact National Instruments."

NI's tech support is difficult to navigate, and I don't even know if we have a service contract, so I came here first. Surely someone's encountered this problem before. So, what's wrong? And how do I fix it?
