I ordered a new iMac and researched how to move my PSE 8 catalog from PC to Mac. Following Barbara Brundage's instructions, I first downloaded the trial of PSE 11 and converted the catalog on the PC. To test this, I successfully imported the catalog into PSE 11 on my son's Macbook Pro. I kept the existing folder structure and the files came in with tags organized and correct and all existing albums were intact. My new iMac arrived and I installed PSE 11. I imported the same catalog from my external drive but unfortunately didn't look at Barbara's instructions while doing so. Now I have 20000 files in one folder, no albums, and tags with no organization whatsoever. I realize that I did something wrong and I want to start over, but I can't figure out how to find and delete the PSE 11 catalog and assets on the Mac. Thanks for any help.
