Arduino program error question

Hi
I have just finished my rostock 3d printer and when I went to download the Marlin software onto the arduino I got an error. It says

DELTA_PRINTER_MARLIN_Configuration_h.cpp:731:31: error: CONFIGURATION_ADV_H: No such file or directory
DELTA_PRINTER_MARLIN_Configuration_h.cpp:732:30: error: THERMISTORTABLES_H: No such file or directory

I have the configuration_adv_h file and thermistorables_h file saved to arduino. I was wondering what I have to do to fix this error?
I don't have a lot of experience programing arduino software so I need a detailed explanation of the fix.
Thanks
Tanner
