I'm interested in playing Ken ga Kimi with ITH, and I used the above guide to set everything up. However, I can't seem to update the version of ITH I got. Neother ITH nor ITH64 works. I am using Win10.
EDIT: Literally nothing happens when I click the update buttons, nothing changes and no text appears inside the box.
EDIT2: I tried again with both the Korean(?) and English version of ITHVNR and although the option to hook the game in, no text comes through. There's only one channel to pick from as well. It looks like this: https://imgur.com/a/SAYwwFF
