Network Tables Error

Technical Programming

Hi guys,

I have code for one of our offseason competitions but whenever I compile/run it, I keep getting this error:

java.lang.IllegalStateException: Network tables has already been initialized
[cRIO] at edu.wpi.first.wpilibj.networktables.NetworkTable.checkInit(NetworkTable.java:45)
[cRIO] at edu.wpi.first.wpilibj.networktables.NetworkTable.setServerMode(NetworkTable.java:68)

[cRIO] in virtual method #47 of com.sun.squawk.VMThread(bci=42)
[cRIO] in static method #3 of com.sun.squawk.VM(bci=6)

It was working fine yesterday at one of our team’s outreach events; however it didn’t work on anyone else’s computer except mine… now today it isn’t working at all.

Im sorta new to command based, so any help would be appreciated.

Thanks
