I think Chris had similar issues, and we're not sure why... But there's a simple solution.
We added a request feature to the "Sorry..." page, so if you go to http://swoape.wikidot.com
and log in, you should be able to request access, and I will manually approve you.
Same goes for anyone else who's had trouble. If you hit the SWOAPE wiki (link above), you should be able to create an account (if you haven't already) and request access.
