I had a 1.7.10 version of factorization, not 1.6.4. I changed to 1.6.4 and now my Forge says that I'm missing factorization : any ...? Um, help?

Hi I have created a modpack for me and a mate, but whenever I try start it it gives me this error: ---- Minecraft Crash Report ---- // On the bright side, I bought you a teddy bear!
