How do I receive my first bitcoin?
It's possible that your firewall is blocking the BTC node connections without blocking the price data. The price data is probably obtained through a normal port like HTTP or something, whereas the usual port for BTC connections is 8333. Other than that, the only other possibility that comes to mind is that it could have not got enough confirmations yet, blockchain.info can tell you how many confirmations your transactions have. Change the address in this URL to your own and see if the latest (top) transaction has 6 confirmations: https://blockchain.info/address/1DFNwqgF1HToPaveeoGZL4qdBDEZYUmC89.
