i tried to change an option a few times, every time i try to save my new setting the game crashes...
the mlog.txt didn't show any errors regarding the font :/
it did show an error regarding the config.xml file. so i'll try with an old ijji config.xml i found.
i noticed my fonts folder in the windows folder was empty, so i'm currently trying to fill it up with the standard windows fonts.
i'll report back when i have some screens etc.
EDIT: got some screens:

EDIT2: adding all basic windows fonts didn't solve the issue above :/
