Please make sure you are not viewing the file with the built-in Notepad program in Windows, as it does not display the file correctly. If it appears all bunched up, as if the Enter key wasn't used, that's a signal to get another editor like Notepad++
The reason why manually typing it doesn't work is the fact that when you view it in an editor that doesn't display the file correctly, the "3" indicating step 3 gets added to the end of the key.
