Aperture 2.1.2 will not start

Question

I have difficulty in getting Aperture to start. I receive the splash screen but that is all I get. In order for the application to work I need to reboot the MBP. The application will come up. However, I close the application and attempt to restart it will not do so.
I have read other comments that you need to reinstall the latest version or reinstall Aperture. Several questions:
1. how do I complete a reinstall of an update? Where do I get the update?
2. is there some thing else that should be completed to make Aperture more dependable?
Thanks

I also had the same problem. Can't use the app as it never gets past the splash screen. However I just found the cause.
Having gone through many of the above steps without success, I thought about what you said above ericNL. My current set up is as follows:
a) I have the Aperture library on the system internal HDD (Macintosh HD).
b) I use Time Machine backups onto an external Firewire 800 HDD, but I exclude the Aperture library from this.
c) I keep two separate vaults updated. One is on the same Firewire 800 HDD above. The other is on a NAS server elsewhere on LAN (a Netgear ReadyNAS, which supports AFP protocol).
I have a script that runs on my account login to auto-mount my NAS shares via AFP. I recently changed this to also auto-mount the share where I keep the vault. This is the problem! To start Aperture 2.1.2 successfully I just unmounted the share, and it works fine. I've gone back to my previous workflow, which is I manually mount the AFP share on the NAS once Aperture is already running, prior to updating the vaults. This works fine again.
I was going to raise a support call about this "bug" but I suspect the answer will be that Aperture vaults are not supported on anything other than a Firewire drive, if you RTFM. A bit dumb in my opinion as it makes a lot of sense to use a remote disk as a vault, even on Apple hardware like a Time Capsule or HDD plugged into an Airport Extreme. Otherwise you are tied to vaults on disks physically next to your Mac, then you have to rotate them physically elsewhere etc.
Hope that helps.
