Invalid argument supplied: translation.php on 118

I had the basic version of Hikashop installed and then bought the business edition. I uninstalled the old version and installed the business edition. When i go to the Add A Product page or on an existing product page (maybe others, i Haven't cheked everything yet) I get an error warning saying "Warning: Invalid argument supplied for foreach() in C:\wamp\www\fashion\administrator\components\com_hikashop\helpers\translation.php on line 118"

I also have Joomfish installed. Just thought I'd tell you in case you think it might be related to that since it's a translations file error.

Forgive me if I'm just being stupid and missing something but I've gone over everything and as far as i can tell everything is set up correctly. I've attached 4 images to this which, as far as I'm aware, should cover everthing needed to make translations work but they don't.

You'll notice on the first image that I'm not even shown the language tabs at the top right of the add a product page that allow me to make a translation.

The second image shows that I have French installed on Joomfish.

The third shows the Hikashop content elements within Joomfish.

The fourth shows my language config within Hikashop.

I really don't know where I'm going wrong here. Have i missed a step?

Joomla 1.5.25 and Joomfish 2.2.3

If you mean jfdatabase, yes that it enabled.

What i mean is what you see in the image eglan1.jpg a few posts ago. There is no option (i.e. a tab with the French flag) on the "Add A Product" page to translate any content (like the ones seen in this image on your own documentation pages> http://www.hikashop.com/media/doc/product_form_main.png ) and also the orange error you can see above where the tabs should be.

I've replaced the file however no language tabs are showing still and there are error messages on many more pages now (see attached, all errors point to the same fault)

Excellent. It's working now. Thanks very much for the support!
