Hello ladies and gents of Minecraft, I happen to have a really bothersome problem and hopefully someone can help me with it, I'm rather new to Minecraft so i don't know much about fixing crashes. It started crashing when i wanted to install some mods so i had to download Forge (Which was a real pain for me by the way) and after I finally got Forge ready and started up Minecraft it kept crashing, here's the report:
