I'm not sure about the 403 error (although when I receive it and have to log in, a page refresh often works), but MC Command Centre is no longer updated and hosted here. It is available on its own site.
I am getting a bit pissed off. All I wanted was to review my original password. Don't remember. Then when I go through the hoops and follow the change password, given a new password and a username, WRONG is the only answer I get. I've waited my 15minutes. And another 15 minutes.
I was very surprised that my email was a hotmail account! That's how long I have been using ModtheSims.
So, what's the word? I would have personally discussed this matter via private e-mail. But that isn't an option either.
