Lost my OpenID account
I created a myOpenID-account for Stackoverflow, and until a few hours ago everything was working fine. However when I tried to login about 2 hours ago, I couldn't, because the user name or password were incorrect (I'm sure I used the correct login data though).
When I tried to recover my account, neither my user name nor my e-mail address seem to have been registered. I was even able to create a new account with the exact same username and e-mail address.
What exactly happened there?
