Full installer (game not working)

[Royko]

Hi there, I'm new to this server and I've downloaded the full installer, then I installed it .. everything went fine and when I click the heRO app on my desktop RO opens and my screen fills up with a border but nothing in it. Its blank and I can still see my desktop trough it (altough when i push my enter button i can hear the RO login sound when u try to login)

Hope someone can help, thanks
