I got my blog back up. I still don't know why Google gave me that message and wouldn't let me in. Seems like everyone else was able to get in okay. I removed some sidebar widgets from the code, and it came back. I put them back in, and it went away, took them away and it came back. I don't miss the widgets. I can't even remember what they were.
So now we know, GOOGLE IS WATCHING.
Thanks for all the comments. You guys are great.
