Error importing textures

I have been trying to insert some textures in png format, but none load, only “Preparing (number of textures)” appears and it doesn´t go beyond zero percent.

Screenshot:

Actualization:
I was able to import one texture out of eleven but the other ten cannot be imported.

I don’t think it was an error in the textures, I think it´s a error in the program, since the texture that I was finally able to import didn’t go from zero to just barely, I tried to add the others, I uninstalled UEFN and downloaded it again but the error remains.
