I want to start a 1.7 world with 2 mods in it, the chisel mod and the carpenter's blocks mod. I have a 1.7.2 Forge Installer, "forge-1.7.2-10.12.0.997-installer" to be exact. The chisel mod says that its 1.6+, so it should work. The carpenter's blocks one says that its 1.7, but I think that its the one not working. I put both of them in the mods folder and forged them and all that but when I try to play, I get this error. (I'm not sure what's important, so I'm gonna put it all here)

So yeah. Not sur ewhat any of that means, but one of you guys probably does! What do you think?

Alright I updated Forge to "forge-1.7.10-10.13.0.1180-installer", so now I have 4 mods, nature, biomesoplenty,carpenter's blocks, and chisel. I did everything I should, and now when I try it it says

"Forge Mod Loader has found a problem with your minecraft installation

The mods and versions listed below could not be found

Mantle : any



The file 'ForgeModLoader-client-0.log' contains more information.
