Mark,
Sure! When I open Creative Cloud on my desktop, on the Home screen, there is an Activity Stream. On that stream it lists what apps have been updated and when. I have an entry that says "You updated Premiere Pro CS6 46 days ago" and a little later another one that says "You updated Premiere Pro CS6 98 days ago" then another one that says "You updated Premiere Pro CS6 Family 170 days ago", etc., etc., These are, of course, mixed in with other updates to my other apps in the MC (e.g., Ae, Ps, In, Fl). Since I knew that the last time DL worked was about 130 days ago (when I completed my last project using DL between Pr and AME), then I could see that (based upon the above), that Adobe had updated my Pr CS6 at least twice since that time.
I do not recall messing with nView, and don't know why I would have anyway, but can't say for certain that I didn't enable it during that time. However, there is definitely an issue between DL and NVIDIAs nView applet that should be resolved by the two of you, especially since the card I'm using is 'approved' by Adobe, and I used the Adobe specs to build my system around CS6.
But any credit for this solution should go to the lone poster who actually discovered it back in July, gagneh, in his post here: NVidia nView incompatible with AME & PPR (Connecting to Dynamic Link Server timeout). Perhaps you or someone should post a sticky (if possible) to this issue for NVIDIA users with a descriptive search friendly title. There is really no telling how many of your users are suffering because of this, judging from the sheer number of posts I've been through on this forum dealing with Dynamic Link issues.
Cheers,
Shane
