Hi and thanks A LOT in advance if you can provide any help (although I believe it is too late for me :-().

Here is the situation. I had some Bitcoins (almost 25) on MyBitcoin.com and I (may be stupidly) decided to send them to my computer.

So, I downloaded the Bitcoin app (I'm on a Mac by the way, in case it is important), and opened it in order to get my address (Let's say for simplicity's sake "Address1"). I then sent the Bitcoins from MyBitcoin.com to "Address1".

Then I decided (even more stupidly I guess) to secure my wallet following these steps (https://en.bitcoin.it/wiki/Securing_your_wallet). Which I followed to the letter. I created the encrypted 256-bit image, moved everything from ~/Library/Application Support/Bitcoin/ to the image and then created the Symlink.
BUT when I opened the Bitcoin app, my "Address1" was GONE and instead I had "Address2"!!! :-(

So what do you think? Am I F**kd? Or is there any (magical) way to get my Bitcoins back home???

At the moment I just left my computer and the Bitcoin app opened just in case...

ANY suggestion would be greatly appreciated :-)
