Hello! I'm sorry if this is a super easy fix, I am new to modding Minecraft, but i followed instructions and I usually catch on pretty quick with modding, but here I have no idea where to start.. I downloaded mods today, put them in the mods folder in the .minecraft folder, made sure I had additional mods that other mods needed when provided and tried to start the game, it started to launch, closed the launcher and then reopened it to the "Game Output" tab.

in it, is all of this:

    Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

     

    Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

     

    DO NOT PM ME WITH PROBLEMS. No help will be given.

    You've installed a coremod built for 1.7.10 in 1.8. Only install mods for the version of Minecraft/Forge you're running.

    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.
