Ii have had some problems also. I just keep trying. Some of them do not seem to require a little bit of time before the registration is effective. You might try contacting customer support. Good luck
You need to register for these sites when you reach the site. Signing into CUTE does not carry over to the others.

I have found that if you go to the blue bar at the top of the page and select home, you will probably have a much easier time signing in.
