I can see that it says This version of FML is built for Minecraft 1.4.7, we have detected Minecraft 1.4.6 in your minecraft jar file But as i said before i have updated minecraft several times and even just deleted everything

Oh yeah im using magic launcher and it worked before when i tried

Sorry for the constant posting. Anyway i tried the minecraft forge 1.4.6 version and it loaded minectaft but not to the start menu just t the mojang logo.
