[TYPO3-shop] No list of products are show in tt_products

[Valentín Miguel]

Hi community,
I have a problem with tt_products since two days ago.
I have install the extensions "table version 0.1.32", the extensión 
"div2007 version 0.2.4", "tt_products version 2.6.1" in my installation 
of "typo3 version 4.2.10".
I have create a page and a template for this page. In the template I 
have add in the constaints the following line:
plugin.tt_products.file.templateFile = 
fileadmin/tmpl_files/products_eur.tmpl
In the include static I add "Shop System Old Style".
In the page I create a content element type plugin->products, and the 
code "LIST". In startpoint I add the sysfolder that I create with a 
couple of categories and products.

But, when I try preview the page no products are show

Any solution?

Thanks...
