Tonight I translated the game using the utility (to english).
I completed 90% of the translation at night, and I was going to finish it in the morning. I was so scared when the utility returned an error when exporting the translation 2 hours before the deadline :D
The reason was in the version of RMMZ 1.3.2, and my not updated utility could only work with earlier versions. It's good that I managed to do it in the end.
