Website verification failed

Hi,

I registered my site http://www.amtex.com.au, prepared the auth file by copying & pasting the content & file name in the confirmation email using Notepad, and uploading the file to the root directory.  But when I tried, as instructed, to see if the file is publicly available, I could not open the file.  Quote: 

 

            Verify that the file is publicly available at:

                 http://amtex.com.au/nortonsw_d68932e0-7767-0.html

 

I found out that my site can only be accessed with the URL http://www.amtex.com.au/........

 

Can this be the reason why the verification failed?  How can the problem be solved?

 

Thanks
