so i have been using magic launcher to download my mods, but some mods i need modloader and when i use modloader it gives me a black screen. i also tried to delete the meta-inf file in the minecraft.jar but it is still the same.
Place the modloader .zip file in the "magic" folder in your .minecraft root folder (Type "%appdata%" in your start bar). Then start the magic launcher, click "Setup", click "Add" on the right hand side of the window that just loaded up, find the .zip file, run magic launcher and your good to go. (If this doesn't work, PM me and we can talk)
