-dont use mcpatcher to install modloader, apply the files directly to the minecraft.jar
-dont try to install 1.2.5 mods on 1.3.1
for now, to play on 1.3.1, make a new world with a clean minecraft jar and wait untill EVERYTHING is updated 100% to install anything. we are just people and need sleep and food too. we cant write a million lines on a day to get you unpatient gamers satisfied.D: live with it. Patience is a vertue
I know I'm sorry! I'm just sorta angry to not be able to install most mods.
