I can't find any Addon Plug in from netgame. Is it from Tools>Options>Main>Add-ons>Manage Add-ons>Plugins?
I tried downloading and installing the launcher thing but nothing seems to change. Is the launcher thing you are talking about from the netgame main website(blue colour web)? From the downloads there are both for IE and FF and i installed the one with FF(NetgameFLC) files. Still does not work.
