WP e-commerce Tag navigation

Hi
:
The Tag navigation in the website I’m working on is redirecting to the Products page.
To show you an example: for the Mayan culture tag, the first or main page is getting linked and displaying fine:
http://www.stock-photos.mx/tagged/mayan-culture/
.
And then when I place the cursor over the Next or 2(º Page) it shows this in the status bar and source code: http://www.stock-photos.mx/tagged/mayan-culture/page/2
.
But instead I’m directed to:
http://www.stock-photos.mx/page/2
.
Every other type of navigation like the one in products page, categories and search is working fine.
And I already changed and tested the code on: product-template.php as indicated on http://getshopped.org/forums/topic/pagination-not-working-in-tag-archive/
, but that isn’t working for me.
.
Hope anybody can help; navigation has been really the only problem I’ve encountered with this plugin and why it stopped to be my first option of a plugin than enables free e-commerce capabilities.
