Yes I tried EP, and I don't really have the time right now to rearrange a huge database, haha. I signed up for a website called Inventorysource.com as a dropship supplier. So far so good. They give you an easy populate data export option that works somewhat OK, haha. I couldn't get all the products on my site, even after I split the files, So I signed up for their Automated service, and I'll be damned if they didn't have 50,000 products onto my site with in a couple hours!
I logged onto my server and noticed they placed a couple PHP files on my server called:

xmlPopulate_zencart.php, and xmlPopulate_zencart_db.php

I'm not sure how they run this, but would like to know how they did it.
