I've been running around getting all the mods that were in the Diamond Dimensions and trying to run them on forge for my friends, but they don't seem to work. I can't even load up minecraft without it reporting that a error happened while launching and caused it to crash.

ps, I'm very new to computer modding and Minecraft in general. I don't what it means by Versions at the top of this reporting system. I am running 1.7.10.
