In my mind you have to ask some help from HWDVideoShare's authors. I do not have such extension...
I got the same reply from them to ask here.
So I'm not sure where to go from here.
In the default install from JCommnets there is a com_hwdvideoshare_g.plugin.php and com_hwdvideoshare_v.plugin.php files in the plugin folder so I would have guessed these should also have been updated.
Anyway, I'll ask over there again.
Thanks for the reply.
