Cs-Cart Ultimate Newsletter Not Working

I am using cs-cart ultimate and trying to send newsletter to the users of 1 of my stores!

When I am on ALL stores admin page, then click on marketing > newsletters - the newsletter functionality is shown, but when I click on the store that I want to send newsletters from the stores menu in the header this text is shown:


Access denied

You don't have permission to access the page.

So my question is how to send newsletter to the users of specific store on my ultimate installation using the right store name and store email address sender & etc..
