Attempting to run the built-in updater to update from 3.8.14576 to 3.9.15790, I keep getting to 10% progress and then the error "Please enter the correct API key". Well I have entered the correct key, or so I thought. I went to the Stack Ideas account site, logged in, generated a new key and pasted this in and retried but still got the same problem.

If my licence has expired, this is a strange way of informing me!
