If they are stuck, they aren't stolen. The address is not controlled by blockchain.info, the service does NOT know your private key. Your password isn't working because someone intercepted your email and changed it, most likely.
How did someone intercepted your email. Oops, don't tell me people still don't use https for all connection.

As I said, there is no chance someone intercepted any of my mails.
My password isn't in a mail nor it would be the same.
