Well, there's a couple of information pieces that I hadn't included:
1. I hadn't played for quite some time before coming back on the 25th and trying to access my main.
2. I could play any other character on my account that was made before I left.
3. I could create and play other characters on my account with no issues.
4. If I was banned, I wasn't aware of it, nor was I aware of why I'd possibly be banned (especially since I haven't done anything in some time).
So...yeah, if that's the "Ban Message", you might want to work on changing that, as that looks like an internal error more than a "don't even try it because you're banned" message.
