Associating products with categories within the database

I created a small problem for myself. I accidentally created a category with a subcategory within it. Within the subcategory i have about 22 products.

I wanted to get rid of the subcategory so I deleted it. I backed up the 22 products and when I deleted the subcategory the products were deleted as well. So I went into the database and inserted the backed up products.

The products arent showing up within the zen admin section or the site, but are showing up within the database. I changed the master_categories_id within each product to match the main category I have thinking it would associate each product with the category, but still not showing within the zen cart admin, or the site.

I'm sure i'm missing something somewhere and figured i'd write to see if someone could point me in the right direction.

Trying to figure out how to delete this post. I reposted this thread here:

I think its better categorized in the above thread. Sorry for the double post.
