Parcival

Alright, I'm new to KSP and this is my first mod... So bear with me if im doing something stupid. I downloaded the files per instructions, the parts dont show up (version 1.3) I looked at the file structure to make sure it was correct, everything looks to be in order minus the fact that there is a "localization" folder included in the download that according to the instructions shouldn't be there. I tried deleting the file so that the file structure matches the instructions exactly, but then when i open KSP none of the buttons work. Sorry if someone has solved this problem previously but i didnt see it when i skimmed the forum.
