Yahoo Biz Express - order confirmation page?

I didn't get one this time, should I worry?

I've done loads of Biz Express submissions over the years, and always get the order confirmation page, like an invoice you can print out.

But this time I didn't get one. All I got was a blank page with the words "You have paid".

No email from them either, to confirm the order.

I'm getting a bit nervous now (2 days later, still heard nothing from Yahoo).

Has this happened to anyone else?
