If you are using versions above 3.6 all templates are embedded into assemblies and they are not located in ControlTemplates folder. In this case you need to get the template from the external zip file that we provide after you have logged in under MyClient.net.
After you have successfully mapped the external template the module will start using it instead of the embedded one.
