There are two downloads that I can't get at the moment, so to describe what ones I'll just use what the error page gives me.

"I couldn't download ff9disc3-10 since you miss configured the anti-leech link file. ff9disc3-10 doesn't exist in your link file. Remember that it's case sensitive! Thanks, and please e-mail me back once you fixed this error."

I also got that message on disc 2 part 9, I don't know if any of these errors will occur on disc 4 or not.
