Yes, the same thing is happening to me. I enter my username and password and it doesn't log me in. If I try to register again it tells me I am already registered.
I too and having the same problem. I put in my username and password and then when I go to use the calander it will go back to the log in page like I have never signed on. Then when I try again it just keeps coming back to the main page waiting for me to log on.
I'm having the same problem. I was able to log in maybe a week ago, but have not been able to since then. It says the same thing to me...please log in, I log in, and it doesn't recognize it. Any one figure out how to fix this?
