Problem with minim library. Error in run example file (RecordAndPlayback.pde)

I am a new to processing. I'm trying to create an application to record sound during experiment and I have found an example that seems to work for me.

The program works fine until the phase in which it has to save the recording audio, giving this error message: Any hints?

 ==== JavaSound Minim Error ====
==== You must stop recording before you can write to a file.

Thank you for your attention.

Looks like the hint is in the error message itself, no? Stop recording before saving the file.
