Hy guys! I need some help. I just downloaded and tried out this game: R.A.W. Realms of Ancient War, but already have a problem with it. After I finish the first "map" and I walk into a portal I should get a loading page where I can accept the next map, however I only got the background and no buttons, text, etc. Anyone knows what's this?

it should be like at 03:02 in the vid, but as I said I only have the background. any ideas how to solve the problem?
