Im trying to mod my minecraft I go to bin then open Minecraft.jar and then delete META inf and install my mod but everytime I do that my game freezes. I can't open my world or connect to a server. How am I suppose to install mods without this always happening. I'm getting annoyed I keep having to delete the bin folder then open Minecraft to redownload it.Heres the error report for everytime I try to load a world:

Is it mods like optifine and TooManItems or mods with forge or modloader ?

ForgeI dont have Forge because everytime I put forge in Minecraft.jar Minecraft just shows a black screen

Backup your saves then remove the whole .minecraft folder. Reinstall Minecraft and then install your mods. Launch Minecraft. This mostly fixes the problem, but if not, update your Java. If it isnt updated, reinstall it.

Also another problem can be that you have Windows 8. Maybe Minecraft still isnt supporting it.

my java is up to date mods like toomanyitems work but other mods keep freezing the game when starting a game and joining a server or when the game starts up... when there is no mods minecraft works fine but i want mods
