Do I need to create the eCommerce pages?

As a result of switching between about 3 different ecommerce plugins to see which I thought worked best, I have managed to delete the important pages of my shop...such as shopping cart, products etc. The only page I have is the main Store. How do I get these again so that the shopping cart etc works?

I've been trying to figure it out myself for ages now but I give up! Tried uninstalling and reinstalling the plugin in the hope it would add the pages automatically again but that hasn't worked either :slight_frown:

Thank you!
