Al Bhed Primers: XIX & XX

[Medi]

Alright, earlier, I checked some sites to find out where the last Al Bhed Primers were that I needed, they were XIX and XX. From the information that I was presented with, I learned that these two Primers were in the Al Bhed Home.

So, I used my Airship to land on Bikanel Island, and I went all the way through the Sanubia Desert. At the entrance to Home, there were two Al Bhed saying something like, "There's nothing to see, now that Home is destroyed. Turn Back." So, it wouldn't let me through.

Is there some other way to get them, or am I just stuck, and to get them, will I have to start a new game?

Help appreciated
