Windows Live ID Error 1017

I have a web application that has been up and running for quite some time now using the Windows Live ID delegated authentication. It's been in production for a couple of months, and all of a sudden this morning, it failed with the following error:

There's a problem with the site you are trying to share your information with. Please try again later.

The url of the error page is

https://consent.live.com/pp700/Error.aspx?mkt=en-US&ErrorCode=1017

We require users consent to be able to see what e-mail address they used to log in. Has anybody 开发者_开发技巧run into this before? If so, what did you do to resolve it?

Thanks very much!

Still not sure what the error actually means, but the following forum posts give some more details. Basic problem: Microsoft changed the API and didn't tell anyone, Contact.View should be ContactsSync.FullSync when using the contacts API.
