This issue is due has two possible causes, the first one in which the certificate may be expired, to fix this:

1) go to Tools->Certificates

2) delete the omega certificate

Try to log in again, if the problem persists is likely MSN is down on you region, so there is nothing more to do unless login in through a Web Based MSN service.
