Final Fantasy Hacktics

Using FFTac Editor , I'm facing this error after having to delete japanese characters in order to pass BOOT.5 and BOOT.7 erros, I've tried everything I found in the fórums still nothing.. Always this error pop up.

I'm looking to a simple patch that increases the random encounters difficulty and variety of enemies, (less monsters and more humans with a variety of classes), and also makes the main history fights harder, having the enemy's level and equips match my party level's.
I have tested some patches and all of them changes too much other mechanics, im looking for straight harder enemies. 

Sorry if this post isn't supposed to be here, just haven't found a better place to post it.

Thanks already and congratulations on this website, im a big fan of FFT and just recently found out that modding is possible.
