In response to post #30894690. Never mind! For anyone who has been having the issue of repeatedly getting that error message about editing files. My problem is that I was editing (and re-editing angrily) the fallout ini files in the STEAM directory. If like me you went to steam common apps to fallout and those changes didn't work, go to users>mygames>fallout and change THOSE ini files. That was my problem, which is now fixed.
