I use a few mods, such as Thermal Expansion, buildcraft and a few others, some of which have not updated to 1.5.2. Yesterday my sister played on my computer and updated Minecraft. So now I can't play on my world because all my mods have not updated. So is there some, legal, way to go back to 1.5.1? I know with the new launcher you can pick between different versions, but I don't know where it stores its bin folder. Any Help?

-Thanks

You can download the JAR from http://assets.minecraft.net/1_5_1/minecraft.jar and (assuming you're using Windows), replace the current minecraft.jar in %appdata%\.minecraft\bin.
