Looks like you have two versions of the program on two different computers and trying to load kids program from NXT EDU (2.0) with updated patch v2.0.f3 to a newer version NXT EDU 2.1 (shipped this fall) without upgrading patch 2.1.f3
First update all patches in the newer version (2.1) and then reload program. In either case it is a issue with Flash 10.1 and compiler issues. I am not sure why LEGO cannot put this info on the bulletin board.
We had similar issue with a new club we started in a Northern Virgina school. Teachers and rookie members have limited know-how about such issues while moving programs from one computer to another.
BTW, we were not able upgrade NXT EDU 2.0 to 2.1 on Windows 7 Professional 64 bit-hardware. Share your experience.

Subject: [VADCFLL-L] "A required file is broken"
Okay, what a morning. I wrote a test program to try out a new design, and
uploaded it to the nxt with out issue. Made tweaks and reuploaded several
times. After a while one of my kids was updating a different program and got
this attached error code. After he got that error on his program. All the
other programs now get that error. Including the test program I had just
wrote.
We can no longer access any of our programs.
