I've tried a couple times recently to use some old 1.4.7 modpacks. Except NEI does not work. And yes, the modpacks have NEIfix in the coremods folder. But it no longer does anything. Any ideas to fix this?
No, the O key, in any combination with other keys, does not bring NEI up. NEI no longer works in multiple modpacks. It looks like something broke the NEIfix.
