Before you tackle any of this, you MUST upgrade to at least version 1.3.9h.

Your version (1.3.7) is VERY shaky now... and is a feast for hackers...

If the store has never been "used", you might want to consider starting from scratch on version 1.5.

It may seem like a "lot" of work to start again... but it might be a good option in your case.

We recently took on a Zc site that had been "off" for more than 18 months (the original owner passed away, sadly).

The new owner wanted to keep the product data, but as the shop had only ever made a handful of sales, retaining customer data did not matter.

We used Easy Populate to export all the product data, and when the new 1.5 store was ready, we IMPORTED all the products into the new store (this time using Apsona ShopAdmin).

The new store took just over a day to create and to populate with product data...
