[RESOLVED] Library problem with a (.h.h)

I apologize for dropping dear PaulS,
as I delete everything and start again, I add the two files DFR_Key.h and .cpp but I do not see the .txt. in README and keywords?

I managed to change the first time but now I can not do it anymore,
thank you for everything you did for me, I think I'm coming to the end,
I hope.
Thank you again and I proceed to the attack to insert the .txt. thank you.
