Overriding node-view-VIEWNAME.tpl problems
The best way to do this is to see what your available theme suggestions are for that node.

In your theme add the following snippet and clear cache, refresh page, etc.

function YOURTHEME_preprocess_node(&amp;$vars) {
   var_dump($vars['template_files']);
   //dsm($vars['template_files']); // if devel module installed
}
