Aperture Library Won't load after update to Aperture 3.1

Question

My copy of Aperture was recently updated to version 3.1.
Since then I cannot get my Aperture library to load in iWeb.
When I opened Aperture for the first time after the upgrade, I was prompted the the library needed to be upgraded, so I'm guessing that iWeb is not able to work with this upgrade.
Has anyone else ran into this issue?
Is there a fix? (I checked for updates, but it says I'm up to date.)

* Solution Found! *
After searching through many a forum I found a solution. (Actually I found it a couple of times, but I had a little trouble figuring out how to delete a file from the Aperture library (a package.)
Here’s what worked for me:
1) View the package contents of my Aperture library (right click on the file in Finder and click on view package contents)
2) Find delete a file named ApertureDatabaseTimestamp in the iLifeSharing folder.
3) Change the permissions on the iLifeSharing folder to read only so this file cannot be re-created.
I also found some posts which indicated that tiff files with invalid dates could also cause the problem. In this case, the resolution was to update the date.
