First of all, welcome.
It sounds like your mod folder is called RFC Dawn of Civilization v1.10, which is definitely not right. Does this folder maybe contain another folder called RFC Dawn of Civilization? If so, move that folder into your Mods folder and delete the other one. If not, just rename the other one to RFC Dawn of Civilization.
