MSN: FailedAuthentication Profile accrual is required

I’m writing a PHP MSN ‘framework’ based on MSNP15 at present, This evening the SSO authentication failed with the following message: (Apologies to not having exact XML)

wsse FailedAuthentication
Failure Code: Profile accrual is required 

The cause? MSN has updated the protocol? Nope, I needed to update the profile for that account, upon logging into MSN messenger with it i was asked to fill out my Birthyear and Country. Upon entering those details in its once again working nicely.

Why blog about this? Well, Why not? Google didnt have any comments for the given failure code, might as well get an explanation out there :)
