macbookpro osx10.9.4 - chrome browser. 3 wks ago re-installed picasa3 [pi]. Added more pics to hd & pi would scan them up ok and add them to the previous pics-but after a little while these newer ones would disappear from pi's folders. Un-installed pi twice with ccleaner & cleanmymac2. Spent 10 days with picasa help before they gave up -re "no mac experience"
have rebuilt pi's data base but am short of 'db3' & 2 "plists" in macs library folders for application support and preferences.
Help !
