Oh thank god! I know how you are freaking out...the same thing is happening to me. I thought my account was hacked! But looks like the site may be having technical issues. I can't call disney right now but if it's not back by lunch I will. Please post here if yours is fixed.
Just check it later. It's been glitchy the last couple of days. That doesn't excuse the whole mess with MDE, but I've learned to not worry and eventually things pop back up.
