WD Elements Smartware backup

I live in New Zealand and am unable to purchase the smartware for my WD Elements.  I purchased the drive in New Zealand so this is extremely frustrating.  What do I do when the software runs out in three days!!

You can use the hard drive like a regular external hard drive for copy/paste file management operations. You can also use another backup software utility of your preference or even Windows Backup in the control panel.
