Shoutbox

i have a problem with the contact card. i installed MSN Messenger 7 and then set up a MSN Spaces account. on the contact card it then showed info about my space such as latest blog. i then realised that i wanted to change the URL for my space and so closed my old one and set up a new one. now when i go the contact card it says "We can't get to this space right now. Please try again later".
it seems to think i am still using the old spaces account. is there anyway to clear all info or something like that.
any help will be great
PS: i know this is mostly my fault for downloading beta software and expecting it to work. also i realise that i have done something in an order that is quite unexpected and so is unlikely to have been tested beforehand.
