Invalid origin name, so mod not installing correctly

I get this message when trying to install STEP textures:

The guide says I need to make sure the textures are in the archive tab but it is not there, how do I fix this? The esps for the textures are not there also :/

Nevermind guys I fixed, I just had to reinstall the mod and it worked...weird.
