I have updated to Zencart v1.5.5e from 1.5.1

I installed Easy Populate which I procured from this web site (EasyPopulate-4.master-ZC)

I followed the install directions but when I go to my admin page -->Tools ---> Easy Populate 4

I receive the following "403 Access to this resource on the server is denied!"

I do have admin access to the site but I'm not sure if I need to change a permission or if this is something that the host has disabled, i'm not sure if the previous posting of this problem has the same relevance

Any help would be appreciated
