Wrong Masterfile connected
I am using Aperture 3.1.2 and have stored most of my images on an external network storage (NAS).
Now I now found several of my images showing wrong content. At first I thought it might be the thumbnail, so I tried to rebuild the thumbnail. This didn't work so I checked the connected master file. It seems that somehow Aperture connected several images to wrong masterfiles. The "Locate Referenced Files..." option doesn't help since the files have different names.
Is there a way to reconnect to the correct master again? This would really help since I have made adjustments to the images I don't wanna lose.
Aperture 3, Mac OS X (10.6.7)
