[Cerrado] Automatic translation is stuck

Hi there, I am trying to automatically translate producst on enlace oculto. We have approx. 100 products and 15 different languages. I started automatic translation using Microsoft Engine. Translation is running for the past couple of days. Every few hours it goes down for example yesterday evenig there were 182 translations in progress, today there are 75 translations. This is taking very long time. I sent only some products for translation, not all at the same time.

When I send more content for translation I get an error:
