Has anyone ever had a error message comeup when you load an aircraft that says "Sound file ungueltig"? I know "ungueltig" in german means "not good" but how is that when my sound file is from the default 737-400. Also, when I try to set my fuel selectors to ALL, they just go back to OFF when after the error message described above shows. I'm using FS2002, can anyone help me out on this? Thanks.
