I'm still a few days out from check-in, but there were reports earlier this week and last week I think that many people were getting errors as well. Good Luck and I hope they get the bugs figured out so you can get checked in (and I can do it next week!)
I had the issue with 2 different reservations, but all my information was still updated correctly. If you try a second time, you may see that everything has been completed. Good luck.
Even though you are getting the goofy message, it still is going through. I had the same thing last week but when we arrived, it was all in the system as completed on- line check in.
I kept getting the Goofy message after setting the pin code so I decided to skip that page. It seemed to work after that. You can set your pin code at check in.
For 3 days I have been unable to access my reservations. The MDE page comes up but the page isn't complete. Goofy doesn't show up, but it's still not working properly.......
