Hi, I am trying to import some old projects back into my main Aperture library that were previously exported as an Aperture Project/Library. I am able to import them fine, but then when I close and re-open Aperture, the project is duplicated x3, so I have 4 copies of the project.

Now, when I have attempted to delete any of the projects, Aperture is crashing on me, so I'm now unable to do anything.

Any help much appreciated!! Thanks  : )
