Hi, I have bought the sitemap generator and have copied all the files to the root. But when I try to install it in admin pannel I receive the following message: File does not exist /admin/applications_addon/other/sitemap/sources/license.txt In the installation guide it says: admin/applications_addon/other/sitemap/sources/license.txt (it will need to be created if errors persist) Sorry, I am very new to this. Should I have this document sent manually or???
