Where did you get the original game from? When you say "spanish version" do you mean a version specifically distributed in Spain/Spanish speaking countries, or that you have selected "spanish" for the language when you first started the game?
And where did you get the patch from?
If both are from the same source (both Gamersgate, or both Steam), everything should work just fine.

Option #2 should not cause any trouble, assuming you installed it on the dedicated HD from the start.

Try reinstalling CK2, and then try to install the patch again.
