HikaShop Content Module and SEF URLs gives 404

Hi When I turn on Standard j1.6 SEF urls (Search Engine Friendly URL = yes, Use Apache mod_rewrite = yes, Adds Suffix to URL = yes)
I get a 404 when I try to access the catalogue from the HikaShop Content Module.
Is there a correct setting for this or does SEF urls simply not work with the HikaShop Content Module?
Appreciate any assistance.

It works but you need to set the "menu" option in your module's hikashop options.
