Today's new Xbox Live feature, Game Room, doesn't work yet.
Kotaku reports that after downloading the two required files the Xbox 360 service does not load properly. And trying to load games in Game Room causes the screen to hang.
There's no word on whether these problems affect PC Game Rooms.
Game Room is a virtual space for you and your Xbox Live Avatar to fill with arcade cabinets of old. You'll need to buy them for 240 MSP (£2/€2.80), but you can test them in true coin-op fashion by plugging in 40 MSP (£0.34/€0.47).
Decorations are bought or earned for reaching high scores in various games.
