I also had a similar situation. I had a full member account until I wanted to change the password and strengthen it with a secret answer to the question in case I forget his password. When you enter the answer to the question in case of loss of access to the password, a message was displayed that it is not advisable to do this, and then the account was blocked by a similar inscription. No matter how many I addressed to the addresses indicated for the purpose of its restoration, I received no reply. This not normal. Moreover, if I typed the name of this account and the password to it, the browser completely locks and I have to reinstall it. After that, I started using a different account.
