using v1.3.9d

OK I have a tricky situation.
I created a zen cart store and used Easy Populate to upload 1300 products.

Everything works fine except when you go to add new products.

I cant add new products and it looks like it points back to a bad database.

What I want to do is delete the whole thing and start over because nothing I do seems to fix the issue.

Is there a way to copy all of the settings (CSS,pages,customization etc.) minus the products and basic files so I dont have to customize the new cart all over again?

My goal is to have a fresh install but use some of the old code that I customized for the appearance.

I cant figure out any way to do this easily. Am I right?
