New C++ Error after mandatory update

After we made the mandatory update in C++, our ability to tune PID failed -- it starts to work, and then we get an error that appears to kill the motors every second or so. (Please keep in mind that our code worked fine before the update).

Interspersed between our printed data, we get:

0xcd99b8 entered connection state: GOT_CONNECTION_FROM_CLIENT
Starting task: Server Connection Reader Thread
0xcd99b8 entered connection state: CONNECTED_TO_CLIENT
Bad message: A server should not receive a protocol version unsupported message
0xcd99b8 entered connection state: SERVER_ERROR
Close: 0xcd99b8
Task exited normally: Server Connection Reader Thread
task 0x11177f0 (FRC_Server Connection Reader Thread) deleted: errno=9 (0x9) status=0 (0)

We are also getting

Bad message: Unknown Network Table Message Type: 128
Close: 0xcd99b8
Task exited normally: Server Connection Reader Thread
task 0x11177f0 (FRC_Server Connection Reader Thread) deleted: errno=9

This problem is occurring whenever the robot is on, including when it is disabled. We have print statements to show our shooter rate data every 20 loops, and these errors are interspersed at rates that appear to be inconsistent with the main teleop while loop.

Any assistance that anyone can provide would be very appreciated.
