Having a 'funny' problem with the installation of AFter Effects:
--
The problems seems to be on several different mac's:
Pb's and Workstations alike.
After Effects seems to register on the s/n, but on next restart, the app
seems to want to be registered again.
(The Activation option from within the app is grey and there's no activation
alert/reminder upon registering the app.)
After Effects seems to work fine as long as the machine stays open, but as
soon as it is retsarted - one has to reg. anew.
After restart, the Trash contains:
Recovered files/Adobe/Bridge/Opera/
and then in this last folder (side-by-side): acpo, adprefs.ini, Bookmarks, defaults, Keyboard, Mail, Menu, Mouse, Opera 7 Preferences, Sessions, Styles, Toolbars
and
Recovered files/Adobe Stock Photos/
and then (side-by-side): images, urlLink.url
Under the images folder there's an 'undertree': FirstRun, ImgDetail, NavBar, print, progress.gif, ShopCart, spacer.gif
I assume that the trashed files has something to do with the problem?

PS.: The common settings for After Efffects in Bridge seems to be 'unstable' most of the time.

Anybody out there has an idea what causes the problem - the installation has workrd for a period of time (a few months), and there's no indication (upgrade of something f.inst.) of what have cause the problem on all machines at the same time...
