You need to put the mod file ([1.7.10]TheLordOfTheRingsModbeta28.2.jar) inside your mods folder to make it work. Otherwise Forge doesn't know where the mod is and can't load it. Also, increase your allocated RAM! you won't be able to play without doing that. Just look it up on google, "How to increase RAM allocated to Minecraft", miencraft wiki should have an article.
