After not playing FTB for a while I decided to look what new modpack/updates there are. I wanted to look at the Direwolf20 (v.1.0.10) Minecraft version 1.6.4 modpack (First time playing) And I waited a while for it to load, I was letting it download in the background while doing something else. Later I checked back on it and it wasn't loaded it was just a launcher (everything clickable blurred out) and the console with an error: "Error: Could not find or load main class net.minecraft.launchwrapper.Launch"
