restoring files as another user
I upgrade from iMac to MBP. Backed up files in external drive and had time capsule doing regular b up for more than 1 year. Erased user and started using new MBP. After upgrading to Lion, moved all iPhotos to Aperture. Most photos ended up as blurry. when tried to open those photos in iphoto an "excamation sign" showed up. after several tries decided to use back up from external drive but did not work. Then tried to recover from time capusule and restore iphoto from the day before I switched to the MBP, but as the user name is different (I guess) the files in time machine are not accesible. How can I restore those files from Time capsule to the new MBP, as the computer is different from the one the Backup was made, and the old user does no longer exist?
Thanks!..more than 5,000 pics need to be saved....
