I'm using Forge universal 6.0.1 (with FML built-in. I love that they added that),
Zombe's modpack v6.5.1 for 1.4.2 (regular, not forge compatible version, not necessary since FML is compatible with modloader mods),
Rei's Minimap v3.2_05 for 1.4.2,
OptiFine HD A7 Ultra for 1.4.2,
Mine Little Pony v188.8.131.52 for 1.4.2,
Not Enough Items 1.4.2 for 1.4.2,
and CodeChicken Core 0.6.6 for 1.4.2.
Forge, Zombe's and Rei's are directly inside my minecraft.jar for compatibility with Magic Launcher. Optifine and Mine Little Pony are in the internal mods selection in Magic Launcher, and the .jars for NEI and Chicken Core are in the coremods folder.
Here's my error log:
Upon selecting a SSP world and trying to play it, it just says "Loading World". Upon trying to join a server, it just says "Logging In...".
