It seems like the MCreator theme keeps failing because of reading the font data, but I'm not sure what to do I've tried everything that I could find, but nothing is working. I've written like 18 pages of mod ideas right now and I would really like to use MCreator, but nothing works. It could be my computer because I've seen a lot of people become able to use MCreator, but I have all of the requirements for MCreator. Please help me!
