I can't extract my score as mp3!

• Jan 19, 2018 - 07:40

I made this score and saved it. but when I turn it, it prints an error message like the one I attached. and I don't know what it means.

Not only that, when I extract it as mp3 file, It can not be completely extracted and it is cut in half.

How can I pix it?

(very sorry, I can't speak English well. please explain easily)
