Blogger Commenting Problems...(solved)

UPDATE:  Thanks to some wonderful bloggers it seems I have resolved my commenting problem (outlined below) by simply unchecking the "remember me" box when signing into my Google account.  I just wish I had asked earlier!  THANK YOU for all the help!

Has anyone had problems over the last few months commenting on blogs?  I have repeatedly tried to figure out a solution to this problem but can't seem to figure it out.  Sometimes when leaving a comment I have to choose "Google Account" and then it asks to to sign in when I am already signed in and continues to do that over and over  and never lets me post the comment.  AND lately I have been running into this error message:

It is getting frustrated because I can't leave comments on so many of my favorite blogs.  I like leaving comments and thanking people for sharing their thoughts!!!!  Help!!!!

Anyone else??????
