Sorry, I don't know what you mean by "different dictionary", ITHVNR doesn't translate anything it only grabs the japanese characters. And if you mean the dropdown menu with the different threads, I of course tried every single one of them multiple times.
But anyways, after restarting my computer on the next day the problem was solved and it caught every character properly again. I don't know what caused the problem, but since it solved itself it's fine I guess. Nonetheless thanks for trying to help me.
