roboRIO detected but no comms

[SyrusVir]

A problem has popped up recently for team 4553. We can no longer communicate with our roboRIO. We recently re-imaged the roboRIO and installed the necessary Java software. After that, we were successfully able to build and run our code. The next time we tried, we were unable to communicate with the roboRIO even though the console in Eclipse reads that it sees the roboRIO and successfully built the code to the RIO. The Comms LED on the RIO is always off.

Here's the console readout from Eclipse:
