Thanks Filosofo.
I have uploaded again and it solved the problem. Now my blog is up and running. But there is a problem.
I cannot access my WP admin login page. When I access http://www.Myblog.com/wp-admin, it is throwing a 404 error.
Do you have any idea, what this means?

Sorry the file compat.php is present in wp-includes folder but not in wp-contents folder.
It is listed in the upgrade steps that I have to delete the wp-contents folder but the file that is displaying in the error message, compat.php is present in wp-contents folder. I have it in my backup. But do not know why it is asking this file, if it is deleted.
Can anybody tell me why?
