I am having serious issues installing Too Many items mod on Minecraft 1.6.2 using windows 8. I downloaded WinRAR. I open launcher delete META-INF and copy and paste TMI in. go to minecraft and no items. I go back to launcher and it looks like I did nothing. Meta-INF is back and tmi is no longer there. Am I missing a step?? I have watched MANY YouTube videos trying to get this installed for my son and I'm just about to quit and say the heck with it. Any help would be appreciated.
