Installation of "New Blog Templates" plugin

I have installed the plugin "new blog template" into the plugin folder (WPMU) but the plugin dont show up in the settings. It is activated in the network...
I dont know if all the files should be in the plugin directory? (it is now)
I could not find any install instruction for this plugin, just your common installation guide and there you refer to a readme textfile that not exist in the download package....

Please, heeelp.

Kind regard/ Lars
