Obviously something is wrong. That's the whole reason why I mentioned the problems. One of them, the classroom problem, sounds like was a problem with the game and not me and that you found and fixed a bug there. The other, neither of us knows what is causing it. It doesn't really matter if it is a specific setting on my PC, a bug in the code, or any other source of an error. The point is to report problems so that more people have eyes on it to possibly find a solution and to make others aware of potential pitfalls. (Even if it is a problem completely on my end, there are plenty of times that more than one person make the same stupid mistake or have the same troublesome setting or conflicting software)
As for me having the file it says is missing, the error message only gives a partial file name. It is impossible for me to know from that message exactly what file and location it is needing. Also, part of the filename is in Japanese, whose characters I can not read. There could easily be subtle differences between 2 similar characters and I am seeing those 2 characters as the same "letter" even though they are not. It is odd anyway that nearly all of the images seem to use only a standard ASCII character set in file naming, and then in the characters directory there are suddenly 3 images (which are duplicates of ASCII named files in the same directory) using a Katakana character set for filenames. It isn't surprising at all when small subset anomalies like this are the ones that end up causing issues.
I'm not blaming you for the fact that it doesn't work for me. It causes an error for me, and you don't know what causes it or how to fix it any more than I do, and that is fine. However, repeating the same "solution" over and over to me after I've already stated that I did exactly that is not useful. I was more hoping someone who has seen something similar on this game, or any other rpgmaker game, might remember a cause and solution.
Since there are new downloads with some bug fixes, I may try to download once more and play in a different order and hope things miraculously work out differently. If not, I'll just move on to other things.
