I'm trying to install modloader for the first time on my new windows 8 operating system. I downloaded WinRaR like the modloader instructions says and replaced the contents of the folder in minecraft.jar. I did delete the META-INF file like the many instructions say. I opened up minecraft and got a black screen... and so far I'm stumped. Does anyone know if it won't work on windows 8, or if it was installed incorrectly?
