Recover a project deleted from Aperture 2?

Hi all, I accidently deleted the whole project I was working on when I was trying to get rid of just one picture. I know I should look into Trash, but here's the problem: I stored the Aperture library in my Time Capsule (an external hard drive), which doesn't have a Trash, so everything deleted in Time Capsule is a permanent move. The good news is: the project is not too important for me. Just one shooting with my GF. And I've already found a way to avoid making this mistake in the future.

Does anyone know how can I restore this? I know it's still in the hard drive (it didn't even make the sound when it's gone). BTW, Time Capsule backs up everything in the computer, but not files in itself.

Thanks.

Other than Data Rescue II, I think you're out of luck. Not a good idea to use TC (or TM) volumes as working volumes.

Ya, I figured that's probably it. What's lost this time is not worth $99 to me, so I will just let it go. Thanks though, Tony.

In case any Aperture users out there might want to know, here's how one can prevent this from happening. Open Aperture --> Commands --> Customize. Now in the Command Editor window, you will see two delete commands. The one with hot key assigned is Delete, which deletes whatever is selected. The next one, Delete Master Image and All Versions, only deletes photos. So what I did was that I assigned the Command + Delete key to delete photos only, and make the general delete using this set of keys: Shift + Command + Delete. No more mess up!
