Using Easy Populate to move to zen from another cart?

I am wanting to move an entire shopping cart that looks like some sort of cgi-bin cart but the site is using jsp coding. This site has about 1000 items. I loaded EP with no problem to my zen cart and loaded all the categories/subcats (about 100) from a csv file. But... all of the descriptions or pricing were not there.

Is there a way to grab all of the products from one site (the dropshipper) to the new zen cart using site? I only have FTP access to the dropshippers site for the data file and image file.

I cannot get the images to load either.

Thanks in advance!

If you can "massage" all the data into the right columns in the EZ Populate spreadsheet for upload, you should be fine. It's just a matter of getting all the data in the right columns, and using the right column-titles, etc.
A good example is a fresh download from your site after creating at least one product with all the normal info in it.
Then follow the pattern.
