@jnsgioia - Yesterday I did. Today I deleted all products and combinations & reimported the updated csv's because there were several updates to fix - images, meta tag one character too long, etc. I reindexed, cleared cache, cleared browser cache and restarted the browser.
Today products are not associated to any category after importing products and combinations. Now, admin only shows five products and none are associated with any category. Maybe because I don't have a home category showing in admin?
@spidawebs Here are a few lines that include single and combination products.

I think I reimported wrong so will try again but I also need to learn how to do things right, so if there's something wrong with my csv, please let me know.
Thanks for the replies!
