Too many items mod not working?

So i downloaded the mod for Minecraft "Too MAny Items". I dragged it into my mod folder and started playing minecraft on Forge. It loads up, and the screen where it says "Mojang" appears. A couple seconds later, it goes away amd tells me my minecraft has just crashed becaause of Too Many Items. I tried everything, and its not like its happening for every mod. I have other mods installed that aren't giving me the same problem, just TMI. Anyone know the problem?
