So i downloaded the launcher a few days ago and i don't have all of the official modpacks on it. The only ones i have are; Attack of the B-team, Blightfall, Hexxit, tekkit legends and vanilla. Not to mention the ones that i do have (Or try to get) cannot be downloaded due to this error. "Failed to download http://resources.download.minecraft.net/ad/ad7d770b7fff3b64121f75bd60cecfc4866d1cd6" (Thats for blightfall btw)
