I did a complete backup from my Imac desktop to an external hd. i am now using a macbook pro. i need to reinstall aperature to the macbook pro. unfortunately when i copy aperture from the external HD all of the aperture software is not together (only 51megabytes out of a file that should be 1600 megabytes), and there is no complete aperture folder. i hope i am doing a good job of explaining this. any suggestions on how to restore the complete version of the software (and no i dont have the disks it came already installed on my imac).
