[SOLVED]Cannot open Photon Eagle files

Hi, i am new here.
I am trying to open the Eagle files of Photon but i can’t, it shows:

Loading C:/Users/vnr001/Downloads/Photon/photon_v1.0.0.sch …
line 5, column 25: This is not an EAGLE file.

I am using Eagle 7.3.0 on Windows 7, and the Eagle file is in https://github.com/spark/photon/tree/master/eagle/photon_v100
I have also tried with Photon Battery Shield (https://github.com/sparkfun/Photon_Battery_Shield) but the error is the same.

Any Ideas?

Thanks you in advance,

Make sure you git clone or download as zip.

Thanks you for your fast response,
