Final Fantasy Hacktics

So hello everyone. I am a player of WotL since it was release on UMD and now I'm playing it all over again with the hacking tools I found. But there is a slight of problem. This FFTactext program I'm using for my game is giving me an error, specifically this:
DTE for BOOT.BIN[29E334] failed. The ISO is not modifed.


I tried looking at the sections and it has only Unit names and Job names. Since I'm only customizing my Ramza into an exclusive job that I imagined, the 3rd of the first four squires listed at top was changed into the job I picked. Using my common sense, I rewrite it back to it's default name, which is Squire. Then I tried patching it back and it worked. I made test runs, all changes seemed to be applied except one thing, the job name in the battle formation select. I pressed Select, it says my edited description except the job name. So I'm thinking this BOOT.BIN[29E334] is for battle formation job names and unit names.

My point is, anyone would kindly help me around with this?

Bump.
