resource.cfg issue?

So I'm feeling pretty stupid.

I downloaded a mod that came with its own mandatory resource.cgf (mandatory as in the creator said you need the resource.cgf file that comes with the mod in your mod folder) but I already have a resource.cfg file in my Mods folder that came with the base game.

What should I do so that I can have both? I can't have two files in the same place with the same name. I tried putting the mod and its resource file in a folder - that didn't work.

Can anyone help?
