<p>I just reinstalled Bitcoin-qt and exchanged the new wallet.dat file with my old one. The Address for receiving coins is shown correctly in Bitcoin-qt but the balance is 0.00 BTC. The Block chain is up-to-date and if I check the Address with Blockexplorer it says my Bitcoins are still on this Account. Why is the Balance 0 BTC in Bitcoin-qt?</p>
