The generated bitcoin addresses are valid for one transaction. I see that the transaction with the payment is shown as confirmed.

It was a normal deposit and if the funds are not showing on your account yet, contact the support service (they are available 24 hours as far as I know). Just give them the bitcoin address and say that a deposit was made but the funds are not showing yet. As far as I know, Bitmover has encountered this problem before and when he contacted the support service, the problem was solved.

No need to mention the contest as it is not related.
