Try if changing or minecraft version to the latest version, it starts with 9, works instead of using version 8 something. U can change it in ur Technic launcher at mod pack options.
Dear all,
I'm trying to update my modpack in the TechnicLauncher to the 9.1.2. Version, however i keep getting the following errormessage at 66%.
(also not only at this modpack it seems). Anyone knows how to solve?
