HALP ME When I use the technic launcher, Everything is fine. UNTIL I use hexxit and a few others. Hexxit is the reason that I downloaded technic and this is what happened to me: I downloaded technic launcher. I logged in with correct minecraft user name and password. I clicked on Hexxit. It started to load/download. It booted up Monjang logo appeared backwards and upside down. Minecraft title screen appeared backwards and upside down. i freaked out and became sad If somebody can tell me how to fix this? I use mac and have java etc. btw im only 12 so please explain carefully THANKS BRO
