It's not that i don't know how to install tmi, I've done it many times before, it's just that i've tried dragging it into .minecraft/bin/minecraft.jat, I've also tried dragging it into the .minecraft/versions/1.6.2/1.6.2.jar file as well, still nothing. Again i know how to install it, i just need to know precisely where to drop the tmi files to, that's all!

P.S. I'm using the new in-development minecraft launcher, if that's important to installing this and other mods properly, thanks!
