Hi Bart,
I don't really work with Tradeos to be fair, but looking into the issue you're getting, I'd just make sure you're using a key that is still valid and working. If you still are and you're getting that error from Tradeos, I'd look into filing an issue with them, because there needs to be a change on their part to make this work.
I know of nothing that would've broke that link between the translate API and Tradeos.
Maybe someone else who's hanging on this group knows the solution.
Cheers!
