Flat Earth Removal in PolSARPro Issue

Hello to everybody, I’m following the tutorial on PCT with PolSARPro, when I perform the flat earth removal with the file flat_earth.bin I generate with the PolSARPro Simulator, the bmp image i get still has the ground phase fringes. Is there something Am I not getting something or there’s a problem? Also when I try to perform the flat earth estimation I get an error about a non existing file.
