When you say that id does not work do you mean that you are getting the same result or a different result that is also a failed result? Did you use the code sample that I provided and ensure that the page was uploaded?
I tested this code by extracting it from your confirm page and put in in place on my own confirm page. I then made sure to update the account details to the ones that you are using.
If you have any further trouble with this please post back with the confirm page in a zip archive attached to your post so we can see just what you have.
