There are three injectors there. Which one do you actually need? Do you know?
Yes, I know, it's the one called: "brainblasted_InjectionTools.ts4script "
The other two files are probably for modders and I don't know if they're broken, the one I gave was listed as broken and it actually shows LE in the game.
It would be best if all 3 were updated, because modders would benefit from it too.
I don't know what mods support this injector, but it's definitely important, because information about its broken version appeared in official news, I kindly ask You to do whatever You can to make this injector work, maybe there are some messages on the page I gave You about this injector that You can read as a modder, as a player I have no idea how it works
