I have a tank drive robot that I've been using to test code. I just installed all the updates to the RoboRio and Eclipse. They have all been updated as far as I can tell.
I uploaded new default arcade drive WPIlib code to the robot and it claimed to have been successful. However, when I go to the Driver Station, there is no robot code. There are no errors other than "ERROR -44019 FRC: the mDNS service is slow to respond. Check firewall settings.", but I don't think that is what is causing this problem as I have seen that same error before.
Right before I updated the roborio and eclipse I had been running the robot with other arcade drive code and it had been driving perfectly. It only stopped working once I updated the robot, which makes me think that something is either set up wrong or there is a huge bug in the updates, and that it is not that the roborio is broken.
The Roborio lights are all good except the COMM light is red, which means that there is no code on the roborio despite me "successfully" deploying code to it.... When I deploy code, the COMM light goes away, and it only turns red when I try to connect it to the Driver Station. Upon further investigation I have noticed that the COMM light is only red when connected to the driver station, and otherwise is fine.
Here is the code I am using. I haven't done a thing to it since I just downloaded it from wpilib.

Any ideas on what to do?
