This error appears if you change your Bing Ads username or password. Changing either of these will break all uploads that were scheduled with the old login credentials. To solve this, you have to delete the old uploads and reschedule them.
I've had an upload running successfully for some time, but now I get an "invalid credentials" error. What's wrong?
