When I go to the mod list it says "No mod information found" for the RotateableBlocks Core. This is preventing me from using the mod as you would guess. I'm not quite sure what's wrong with the file but I have tried reinstalling it and had no luck.

Why would not having information on the Mod List for the Core prevent you from using it? I don't see the issue.

I don't know. The rotatable blocks mod just doesn't exist ingame unless the tool is in a specific category like tools, combat, etc.

The wrench must be enabled with

settings {
B:enableWrench=true
}

and its under tools, it has no creative tab of its own since its just a single item.

Also tested, and its working fine.

Thank you.

Wait, where do I go to do that?

in the config/ folder theres a RotatableBlocks config file, its in there.
