Posted December 31, 20159 yr So basically, I haven't modded Minecraft in years (literally) and I decided that I would try again. I installed Forge for Minecraft 1.7.10 (I tried Recommended and Latest) and both of them made the launcher close, then reopen with a giant error. I think this is because I've set it so Minecraft automatically reopens the launcher when it closes, so that means that the game is instantly crashing before any visuals come up. The full error log is at: http://pastebin.com/9c3YatJu
December 31, 20159 yr java.lang.NoClassDefFoundError: net/minecraftforge/fml/relauncher/IFMLLoadingPlugin You're trying to use a coremod built for 1.8+ on a 1.7.10 client, this won't work. Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
