I've tried every version for 1.6.2 so far, but every time I instal it and start to launch it, it just doesn't work. Close to the bottom, this shows up:
file:/C:/Users/Gray%20Family/AppData/Roaming/.minecraft/versions/Modded1.6.2/Modded1.6.2.jar!/net/minecraft/server/MinecraftServer.class appears to be corrupt! There has been CRITICAL TAMPERING WITH MINECRAFT, it is highly unlikely minecraft will work! STOP NOW, get a clean copy and try again!
Client> 2013-07-09 08:23:38 [sEVERE] [ForgeModLoader] For your safety, FML will not launch minecraft. You will need to fetch a clean version of the minecraft jar file
Game ended with bad state (exit code 1)

I have downloaded .776, .780, and .781 more than one time and installed them, but I get that message every time. Can anyone help me out here?
