I've been using CC for years - just started getting this message yesterday. Help!log.txt
any chance you were still in Chrome, or had one of it's background tasks still running?
No, except that CC keeps having to force Chrome to close.
in the pinned topic Quickie CCleaner FAQ, in the Problems area there is something on Goggle Chrome that may help you.
basically it points to here; http://forum.piriform.com/index.php?showtopic=38438entry233281
see if that helps.
