Each time when i try to open a modpack called Charzipack do i get a message that says: An Error during startup prevented Minecraft from starting The following mod(s) have been identified as potential causes: CodeChicken Lib.
I tried contacting the modpack author, but he said that i should try logging in again (which didn't help), and that he couldn't disable the mod, because that would also remove the Thermal mods. Please tell me how to fix this or what the modpack author can do.
