Me too second ticket i update for that 404 error, each time i get a reply the same day saying it was fixed.
I try it and it doesn't work, i won't be updating the ticket no more... Just will try in the morning, at lunch time, during the night until it works
May be the fact of lowering the amount you can load each day as an effect for some users but not for me. Its a real question of luck if it works in my case...
