I checked your account in our database, and it looks like it hasn't been activated properly yet. You'll want to make sure that you've clicked on the link that was sent to the e-mail address that you used to sign up the account. Once you've done that, you should be able to log on within 48 hours or so.
If you've already tried that, make sure you're keeping the "Play Game" tab open while you play. If you're having problems staying connected, you may want to look into a page refresher. (If your computer is particularly derpy or has connection issues, this may be something you need to make sure you've got a solid connection.) The characters showing in a black void problem can likely be resolved by going to the main page/homepage of the website and accessing the "User Panel,' where you can reset and then send your characters home.^^
The character changes not loading might be resolved as soon as you fix the connection issues. However, it's not uncommon for that to happen, even with a decent connection. I myself have had character changes not saved, but I usually resolve it by making tiny edits and saving frequently, rather than trying to create an entire character to finality and saving it then. Unfortunately, we're not exactly sure why it happens.
