I was finally able to submit a little while back, after trying every day for over a week. The only difference I noticed was that when I was successful, I submitted it early in the day, during business hours (it was like 10 am Mountain time, I think). All the other times I had tried at night. So maybe the ticket is to try early in the day?? Good luck with it everyone, I honestly was close to just saying to hell with it, when finally it just worked.
