I hope someone can help, I have run into a problem with converting a recipe to the txt format. Here's the command I issued:

ebook-convert "Ars Technica".recipe Ars.txt



it almost completes the conversion then at the end an error messages spits out:


[...]

I hope someone can help me with this.

Thank you!
