Hi,
The description suggests that the products (defined in Tools - > Ecommerce) were not deleted, only the product documents were.
The product documents are linked with the Ecommerce product by NodeSKUID column in the database record for the documents (more exactly TreeNodes from CMS_Tree table).
So, what you need to ensure setting the proper NodeSKUID of those documents to the existing products (SKU) SKUID values.
This can be done in the database, but that's not recommended if it's not the very last option.
Easiest way would therefore be (in the
CMS Desk) to select the product document that is not linked with a product and in the
Product tab, choose
Mark document as product option and
Select an existing product. You can see the closer description in context help (pointing to ~/CMSHelp/index.html?cms_content_product.htm)

Zdenek C.
