Though I posted to Amanda about such in my original thread about this issue, my newly created email is now doing the same thing as my original (Invalid OpenID or Credentials). I'm loath to create a third as I have a feeling it will do the same. It's strange that it worked after creating it, but reverted to the problem of my orginal account sign on within a few days.
Thanks for letting me know! You can keep your updates in your thread with Amanda. I'll eventually find out news from her too, haha.
