What does it mean in SSBB?
I wanted to play SSBB tonight but when I turned the game on,
it gave me a "Receiving vault data..." message with circular object that looks like a clock spinning below it.
It's been 10 mins now and the clock has just been spinning over and over...

You must have lost your connection. I'd try restarting the system. It should only take about 5 seconds to receive data.

Thanks, restarted.

means you got new sampled vids of home run contest ect and custom stages sent to you by nintendo check the vault area u should see it.

You mean I got new custom stages?!
Yes! ^_^
I'll check it out in the morrow. haha I've always wanted to say that ...... in the morrow 

 Yeah,you get one custom stage a day. The problem is that when you go online when the next batch is available, you lose the previous data. IGN has a feature now that allows you to download user created stages from their webiste to your SD card and keep for as long as you like.

i hate how you cant delete the vault data sent by nintendo

:'(... I want Brawl too!
