You don't have permission to access ....fckeditor.html etc

Hi There

I installed nopcommerce on mys server without any problem appart from the fact that I am getting an error message from fckeditor when I try to add a product in a categorie ( it doesn't stop me to add the product but the html editor diesn't show and istead I have the following error)

You don't have permission to access http://www.mydomain.com/store/editors/fckeditor/editor/fckeditor.html?InstanceName=ctl00_cph1_ctrlProductAdd_ProductTabs_pnlProductInfo_ctrlProductInfoAdd_txtFullDescription&Toolbar=Default on this server.


I checked my file manager and check the permission for the folder "fckeditor" and the permissions seems fine (modify ( IUSR ))

any ideas ?

Thanks
