Alright, typically you would get this by downloaded correct versions etc etc, but I have tried manually downloading every version (latest), ModManager, with ur modpack settings, etc... is there a certain version of Factorio I should use? Is there a certain program I should use? just, I am having so many issues to play this modpack ;w;

just for clarification, mods keep error-ing out, and not wanting to load correctly.

This modpack is confirmed to work with Factorio 0.18.15.
I assume that by ModManager you mean ModMyFactory, in which case without specific error descriptions there is not much I can do.
Make sure other mods that are not part of this modpack are not enabled.

Nah, I figured it out, you actually just helped me. 0.18.15 works great.
I shoulda figured it was something dumb like, version not supported.

You can confirm this as solved.
