Access to the Sprite Collection once committed: Unity 4

[Madrayken]

How do I access a sprite collection once I've committed it?
If I go to the prefab in the project panel, I don't see a link to the Sprite Collection editor in the inspector.
If I click on a sprite in the scene, I get the option to 'Edit' in the dropdown box next to the Collection drop-down box, but clicking on it brings up an empty Sprite Collection with the same name!

What am I missing here?

Many thanks for any help.

Here's a screenshot of what I get: http://www.mediafire.com/view/?3nal1iib1yeof3y

Can you send me the zipped project to support@unikronsoftware.com? This should work fine - I should be able to work out why its doing that.

Just so people know - I got a really quick solution for this from the team (it was a corrupted reference, which they fixed for me). Excellent customer service.
