Problems with my database & phpMyAdmin

Hi,
I'm currently having problems with my database for my ZenCart store, in regards to importing a single .csv file containing the stock taken from TurboLister and trying to place it within phpMyAdmin and each time it get's shot down.
Attempting to input each product individually via the backend of the ZenCart store does not work either, as it keeps giving me an error message of;
The requested URL /ZC/admin/product_XXXXXX.php was not found on this server. (where XXXXXX is the product ranges)
The categories themselves have been setup within ZenCart, but don't seem to be creating their .php files within the site.
The server is a Linux 2.6.9-89.0.19.EL.smp OS, with ZC 1.3.8a installed, using MySQL 5.0.89-community for the database, and PHP Version 5.2.12.
If I've missed any details, ask I'll post them asap, but I would appreciate any help with this matter as I need to get some stock onto the store!
Thanks.

Sorry but this does not make sense... There are no individual "php" files for categories, or products, or any other resultant "page". All the data is contained in the database.

I'm not sure if you understand how this whole thing (ie: Zencart) operates...

Why not adapt your CSV to be compatible with Easy Populate Module, and use that to get the product data into the database.

Thanks for the reply.
ZenCart is new to me, as is SQL & Php. Html I've had a knowledge of for a while, but it's a little rusty.
I'll take a look Easy Populate Module and see what joy it brings...but when I go to add a new product manually through my browser on the ZenCart admin pages, it gives me that message saying the product type .php file isn't there which leads me to believe I still need to fix something...
