Did you bookmark the site when it was still having problems redirecting (the first couple days it was up)? Because that's what was happening when I couldn't get in. I'd log in, it would recognise me, then I'd click on the bookmark and it wouldn't know who I was. It was a vicious cycle. I finally realised that I had to delete the bookmark.
Also, maybe try clearing your cache/cookies and start over?
If nothing else, I can reset your password for you. PM/email me if you want me to do that.
