We closed the program and turned the robot off and back on. After restarting the program, the problem was fixed.
Deleting unattached or loose pieces in the program blocks also helps.

Re: [VADCFLL-L] Help "A required file is broken"
It sounds like you are an unpatched version of NXT 2.1. See the LEGO Education website for the latest patch that apparently does fix the problem (this link originally provided by Julia Marshel):
In case this isn't it, here is another interesting post from John Barrett of the Cellar Dwellers last year on this subject:
My kids discovered that if there is a "bar" somewhere on the screen [unattached], then the program will not compile and download. By "bar", I mean one of the connectors that goes between blocks. Sometimes they are hard to find.
You may need to recreate the program (as in create a completely new program) and copy the block values over. Cutting and pasting blocks from the old broken program to the new one will sometimes grab the offending bar, so beware if you try that approach.
