I just realized that I've updated to Manchester U1 since you last posted and haven't experienced a single one of these message loading or exiting Sonar.  And I never have CCC running, but I am online.  Just to make sure, I just turned my wifi off and still no messages (thank the Gods).
 
Odd that Willy says it's inevitable.  I hope it isn't.
 

I've been getting this popup message lately on my 2nd PC, but not on my primary DAW PC.

Strange. As long as your logged into CC you should not get the message on any PC

It's OK now. After launcing Command Centre just once I no longer get the popup.

I'm not logged into Command Centre very often. I normally use the offline installation method.
