[Plugin: WP e-Commerce] URL & Product Page problems

I installed as instructed, and Having lots of difficulty understanding — what is going on here.

WP Version: 2.6.1
WP Shopping Cart Version: 3.6.8RC1

It looks like there is no product page? So, I click a product, and it gives me a 404 error. I am using permalinks, and it takes me to page that doesn’t exist. When I turn off permalinks, it loads the main WP index page, and doesn’t display any additional information.

My .htaccess file:

<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

E-commerce > Admin > Settings > URL Settings:

https://we-sell-time.com/products-page
https://we-sell-time.com/products-page/checkout
https://we-sell-time.com/products-page/transaction-results
https://we-sell-time.com/products-page/your-account

An example URL of a product (you can view my index page for the products I have added):

https://we-sell-time.com/products-page/packages/1-day-of-time/

Can you tell me how to get this working?

Thanks,
Marcin
