I got a new computer and installed Elements 9.0 on it. I am retrieving the pics from my old hard drive just fine but I seem to have lost the majority of my old keyword tags. Any help? Thanks.
If you didn't write the keyword tags to all the photos when your old computer was working, you can't get the tags back by simply retrieving the photos.
You'll need to retrieve the entire catalog directory. When you open that old catalog on your new computer, all your photos will be listed as "missing". Use the Reconnect All Missing Files to connect them by browsing to their current location.
