I not found the file

I replace your file but I don't see the product in the site but only in administration panel!

You don't see the products? Why mess with fixing the issue with the categories module then? You possibly have not corectly assigned the Category Template inVM Configuration/Templates or have an old menu link to categories? See http://forum.virtuemart.net/index.php?topic=120433.0 for that.
