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
