Let's guess on the available information:
- you have no computer
- it's not switched on
- it is working but you don't know how to use it
- there is nothing to snipe
- you're not registered on Ebay
- you're not registered with AS
- there's a bug of some sort
As mentioned elsewhere, you might want to log a support call but give them a bit more info. so that they can tell what the problem might be and solve it for you.
