It's illegal to redistribute those files.
Although some one here might send them to you, I wouldn't be put your email address out for everyone to see if I were you..
Worst case if no one will send you the file, you could always to a fake FSX install on another computer, if you have another computer, then get the file off it and uninstall it. Or, maybe try an FSX "repair" but I would be hesitant to do that since it could mess with other things in your install. I did need another file like that once that I forgot to back up, so I just did an FSX install on my internet computer, didn't activate it, pulled the files I needed, then uninstalled it.
