Ok I've tried searching quite a bit on these forums and haven't really found an answer. My apologies if this has already been answered previously.
Oh and this is my first post on here too.

Pretty much what I'm trying to do is use Tactext, FFTPatcher, and ShiShi to create my own custom classes. I'm able to do that on a clean ISO but after I patch it with FFT1.3 everything pretty much gets buggy and all the text changes I made revert back.
Now I know I'm able to use FFTPatcher and ShiShi on a 1.3 patched ISO but for some reason, Tactext won't load the ISO and gives an error that says:
"Error Loading File: The given key was not found in the dictionary."
So my questions are:-What am I doing wrong?
-Can I edit Text in WotL after/before its patched?
-If so, how?
Thanks in advance for your responses.
Also I really love what your community has done for such a wonderful game and the work that I've seen all of you do has rekindled my passion for my favorite FF game.
EDIT: Turns out I had an outdated Tactext program...
