Final Fantasy Hacktics

Hello, everyone.  I'm a newbie here, and have just recently become familiar with the hacking tools I downloaded from this site. I am currently having a bit of a problem with the new version of Shishi Sprite Editor.  

Whenever I open a fresh ISO file with the new version of Shishi, my game crashes soon after Ovelia finishes her pray in Orbonne when starting a new game.

I also get this message:

readfile:buf=02b26b20 len=96 err=38 [reached the end of the file.]

Can anyone help me resolve this issue?  It would be much appreciated.

I don't know. Maybe it's your ISO? Are you sure it's clean? Or maybe it's corrupted?

Well, have you played your ISO before opening it with ShiShi?
Hmm.. I'm not sure.

ShiShi is not for event sprites, but I think it might have to do with the extending. Hmm..

Yes, I played the ISO before using Shishi and everything ran smoothly.  I used Shishi to change the sprite for Ramza 2/3 and when I started a new game, it crashed shortly after Ovelia's prayer.  I ripped a new ISO, opened it with Shishi, then immediately closed it.  I started a new game and the same thing happened.

I ripped another ISO, did not use Shishi, and everything ran smoothly like before.  I then extended the ISO, opened it with Shishi, changed the sprite for Ramza 2/3, and once again the game crashed shortly after Ovelia's prayer.
