Keep Getting error in TacText please tell me what it means

[Furry_Fan]

Ok, I have been messing around with the text editor and have managed to change Bard in all instances to Dark Knight and Dancer to Devout.  the problem is when I loaded the game it was all working fine on every screen and looked normal.  So I decided to do more Text hacking and tried to change Ramzas squire class into Heavenly Knight then I started getting this error DTE for OPEN.LZW failed. the ISO has not been modified.  Now I was under the assumption that I had too long of a name (though it seemed to work when I changed Bard to Dark Knight flawlessly) so I tried a generic Holy Knight because it was shorter.  again I got DTE for OPEN.LZW failed. the ISO has not been modified.  so out of curiosity I changed the names BACK to there originals Dark Knight back to bard Devout back to Dancer and I STILL get this error I cannot edit job descriptions or anything and I really do not know what the error means in general.  Could anyone please explain this to me a little better or tell me what is wrong.  I really appreciate it.  Thanks.
