Games : My Minecraft Single Player World is not loading (I am using forge)

I'm having problems with my minecraft forge. I got my mods installed and I load my saved singleplayer world, and as usual, I see the loading world page but then it takes me to the Minecraft Menu Page. And then I try again, and it does that again, I tried it with my other worlds, but it's the same, and it doesn't work.

Details: Version of Forge that I'm using: forge-1.7.10-10.13.2.1291-installer

Mods that I'm using: -Lord of the Rings -Minepainter -customnpcs -waypoints -Mr crayfish's furnitures mod

Java: 32

I'm asking for the answer as soon as possible because I am doing a school project on this and its due next week.

Thanks!
