I started a new world for the update but can't upgrade the building block. When I click to upgrade I get an error message. Anyone else have this problem?

Will it update in the modlauncher as well? I tried manually installing and keep getting errors.

Hello, I heard about this mod and I have been trying to play it now for 3 days and it won't work.. I use the Mod Launcher and every other mod works but this one, what can I do to be able to play it? Is there a step by step process for the non mod launcher one?
