I have to apologise; since Valve decided to spontaneously disable access to game hubs from accounts with VAC bans, I have lost the ability to update this addon. Although my VAC ban occurred roughly 9 years ago, this newly added restriction means I cannot push updates. Since it's unlikely Valve will bother doing anything about it, that's the state of play for the forseeable future.

Thanks for responding, its a shame to hear that.
