How can I fix this issue with Formation Tactic Editor?

[Bador]

I created new formations in the Formation Tactic Editor based on the formations contained in the MyFormations folder. I imported these new formations into the game using the Formation Tactic Editor. After importing them into the game, a file named formdata.big appeared in the MyFormations folder. Using FinalBIG, I placed this new formdata.big into the archive zdata_16.big, replacing the existing one there.

As a result, when I start the game, it crashes before reaching the main menu.
