Errors often report Robot Main just because it calls everybody else. Robot Main is essentially your program that's made up of a bunch of sub-vi's. Take a look at the vi's you've modified from the default baseline to see if any of those front panel arrows are broken. The most likely candidates are: Begin.vi and Teleop.vi.


Are you using the Run arrow from the Robot Main.vi front panel?
or
Are you using Build/Run as Startup

Perhaps a screen shot of the particular error message or posting a zip of the project so we can help you find the error...

Break (as opposed to "The VI is broken") might refer to a program breakpoint in execution accidentally inserted into a sub vi like Teleop, but that's only effective when using the Run arrow. Breakpoints show up in the code as a red dot on a data flow wire as in the attached (red dot on the axis 2 (y) output wire).
