Transaction not received

[Klortho]

I'm brand new to bitcoin, and yesterday I installed the client and fired it up, and then immediately went and bought some bitcoins.  I got an email form the seller, saying "Bitcoins have shipped".  But then I realized that I was behind a firewall (at work), and my client wasn't connected.  By the time I figured out how to move my wallet to my home computer, so that I could connect to the network with the original receiver bitcoin address, a whole day had gone by. Now, I have waited (connected) about an hour, but still don't see the transaction.

Is this normal?  Does the transaction have to be acknowledged by the receiver before it gets added to a block?  If so, does the sender periodically resend the transactions?

You need to download the whole blockchain before tx show up. You should see "120960" as of 04.29.11.

You probably don't have all blocks downloaded yet, check your receiving address balance at http://blockexplorer.com/address/insert-your-bitcoin-address-here

Alas, all blocks received, still no coins (see screenshot*).  I see the balance at http://blockexplorer.com/address/17QsAdFUQYG6QNqmD3g5jmzjrfgrrod6BV. 

I wonder, could it be because I swapped wallets after the blocks had downloaded?  If I go and delete the database and re-download, the coins will show up?  Seems like there ought to be a better way.

* Nevermind about the screenshot -- forum says "uploader is full".

Start the client with the -rescan switch. (Or with -? for more commands).

Backup your wallet.dat file so if you fuck it up somehow you have a hope of getting the coins back.

The -rescan option should probably work. To use this, you will need to browse to the directory where bitcoin.exe is (in win7 it's easy, shift-right click inside the directory and click 'open command window here'), Then type bitcoin.exe -rescan at the command prompt, it should rescan the block chain and start the client.

Brilliant. Thanks for the help, the rescan option works.
Thanks for the tip about the wallet backup as well -- already done!
