Hi, I’m hoping that this will help someone because I was having the same problem. I think what had caused the initial problem was that I had initially tried wp-ecommerce then I deactivated it and then installed the woo-commerce plugin.. But when I did this I noticed that I wasn’t being redirected to my checkout page. (frustrating).. Anyway I noticed in my pages area that I had duplicate checkout and cart pages which I think were initially there because of my initial installation of wp-ecommerce. So what I ended up doing was deleting the plugin as well as the checkout and cart pages and re installed woo-commerce and everything works fine now.
What I did was pretty drastic but I was frustrated and now it works
