Thanks for the suggestion, Rajsfree. FYI, The page
http://helpx.adobe.com/creative-cloud/kb/aam-lists-removed-apps-date.html
seems to be out of date. It suggests for example finding a and deleting
" OPM.db file in the \User\\Library\Application
Support\Adobe\OOBE folder."
In my Mac OS 10.8.5, there is no OPM.db file in that folder, or anywhere
else.
I will try Contact Adobe once again, but I have had enormous difficulty
connecting. I finally got through last night after waiting half an hour,
only to be told that there was none at the necessary specialist department,
and I should try again "during business hours," whatever that means (US
business hours or India?)
