Aperture 3.4.3 simply won't launch from a fresh install

So, I just purchased Aperture from the App Store, and it won't launch.

I tried the advice here:

http://support.apple.com/kb/TS4412

To no avail. Since the app hasn't launched, there is no preference file to delete.

The only other variables, of course, would be my hardware and OS, but all of that is up to date.

I kind of need the app running... Any idea what's happening?

Cheers,

T
