General ROBOTC Issues
The Function Library is empty
The Function Library is the panel on the left-hand side of ROBOTC that shows all of the functions and commands currently being used by the program. It includes all of the major ROBOTC commands/functions, as well as any functions in #include files that are in use and any functions/commands that were created in the program
The Function Library only populates itself when the current program is compiled. To resolve this, either 'Compile' (F7 on the keyboard) or 'Compile and Download' (F5 on the keyboard) the program; this can also be done from the 'Robot' menu inside of ROBOTC.
The ROBOTC Welcome screen displays a 'Your computer appears to be offline' message
Usually when this error occurs, there is a setting, program, or restriction in place on that particular computer or network that is preventing ROBOTC from reaching its update servers.
In most cases, this problem must be solved on the user-side in order for the Welcome page to update properly; however, an installation only needs to be connected to the ROBOTC activation servers once (when it is first activated). Beyond this initial activation, ROBOTC will run without an internet connection without losing any of its functionality.
