I'm having a problem withdrawing 0.92 BTC from my account. I used 'Instant Payout', it shows in payment i did withdraw 0.92. However, when i click on the date, it gives me 'No such transaction', and i haven't received it so far. Been 2.5 hours. Is that normal?
Yes, at this moment. Blockexplorer (the monitoring site which is linked from the date field) is currently overloaded/DDoSed, so it may show "No such transaction" for existing TXes.
You may use
http://blockchain.info to check the status of your transaction. I don't know your account name, so I can't tell you if the payment is already confirmed or not. Usually it takes about 20 minutes, but in worst cases delays up to a few hours are possible.
First, you need to check if your client's blockchain is up to date. It should contain at least 166979 blocks.
If everything is OK with your connectivity you just have to wait a bit more. Since the payment is present in your account report, it was already sent to the network.
