Live960 timeout

Could somebody please elaborate on why does the server abort the game so quickly, telling me "Please do not start a game unless you are ready to play." when I'm playing live960 as white and I don't make my first move within just few seconds? With normal chess it would make sense. But with live960, each start is different, so I definitely need *more* then just few seconds to make the first move...
What does the "unless you ready to play" mean in the context of live960? I thought that the whole idea of Live960 is, that we think instead of going autopilot. So why doesn't it give me the time needed to think? I had 5 minutes on clock. And just because I didn't make my first move within seconds, the game aborted. It kind of disadvantages white, forcing white to make something really stupid as the first move.
