Due to circumstances I had to cancel my hosting and domain name a few months ago but did a part and full backup of my web site through cpanel.

I now want to set up the site on a spare pc at home and am thinking off downloading xampp for this.
When I go to download a new zen cart can I use the latest version or should I use 1.3.9 that I was using before.

How can I retrieve the data in my backups to the local set up.

Many thanks.
