I mentioned this problem a few days ago (you get a sorry! and a shy/blushing Mickey?). Someone replied that it was a cookie problem.
There's a lingering cookie on you PC. Here's what fixed it for me:
I'm on IE 5.5
Tools, Internet Options, General tab.
In the middle, under temporary internet files click settings.
From settings click view files.
From the list that appears sort on the internet address column.
Scroll down to "Cookie: default@disney..." Delete everything that looks like it refers to disney.com or disney/go
Close the browser and start again.
good luck
