Hi all,

After enabling Windows Live Authentication, when i try to login using my windows live id, my sharepoint webapplication redirects to error message page saying "Operation is not valid due to the current state of the object."

I tried this command also stsadm -o upgrade -inplace

Can anyone solve this problem ?
