From your screen shot, it appears you saved the file as "5.htaccess".
You don't want the "5" in there.
It needs to be saved as ".htaccess". Also make sure your text editor is not appending a ".txt" to it either or it will not work.
You could probably use dreamweaver to simply rename it to ".htaccess" and then reload it and you should be good to go.
