I fixed your account and now you can login and use the original email (contact@...) without problems. All your original forums and messages were set back to this account, see:
http://n2.nabble.com/user/UserNodes.jtp?user=414952&node=1(the other account still exists in our database, but it is empty. So you can forget it.)
Please try again and let me know if you still have problems.
