The Windows Live Messenger Team is going to fix this problem, i had contact with them and they confirmed it was an issue with the groups.
I got this e-mail:

Hello Tristan,
My name is Steven; I work for the Windows LIVE Messenger Global Escalation Group.
I understand you are having an issue with connecting to the Beta client, error 81000451.
We have found that this issue is caused after a group is made and deleted/removed in the beta client.
We are currently investigating the issue and we expect to have more information shortly. You can still using the older clients and the WebIM client if you would like to stay in touch with your contacts for the time being.
Thank you for contacting the Windows LIVE Messenger support group.
Steven
So as i said before, we just have to wait
