What is your OS's Update set to? I would assume that you have that turned to Full Manual, so that no updates, of any sort, can be downloaded and installed, without direct input from you. Is that correct?
Any other programs, that might have sneaked in an update, like Flash Player, Java, QT Player, etc.?
Though it sounds like the rest of the display is working fine, I would check for a newer video driver, just to rule that out.
Things were working with that Project, but can you to a quick test New Project, and maybe Import a known good Asset, and then one from this Project?
Hey Bill ( thanx)
I believe that I have all updates in manual mode but thats difficult to tell these days.
Confident that nothing updated though because I am usually notified.
Will try a new project but because I have tried multiple projects with previously working Playback..I suspect some other issue than assets.
Not keen on changing a video driver int he middle of 6 TVC projects with a deadline of Tuesday,
Everything else works perfectly including export via AME
How do I dump the prefs file? ( I have forgotten). IS that worth trying?
See if you have a system restore point you can use or restore using an image backup of your C drive. I always keep a current image backup that I can load from a bootable CD. It has saved me many times.
I have just got it working again after a few restarts but what I think was the turning point was when I played down some files in wmv and QT player before I opened PPRO.
Maybe that gave PPRO a little 'wake up"!
Need to test this further for cause and effect but meantime ..I am editing.
Interesting development. Please keep us informed
The reason that I asked about other programs updating was that fairly recently, I had a large PS Image open, and in the middle of Saving that panorama, Java decided to update. Well, that killed PS, and the Save, costing me some hours of work. It was also the only time, in almost 20 years, that I had to reset my Prefs in PS - never happened before, or since. I thought that ALL programs on my computer were set to ONLY update on manual, and to just tell me that an update was available. I had missed Java, and it bit me very badly. Now, it's on full manual. Hope that I have not missed anything else. I flat hate all auto-updating, and even at diminished levels.
Good luck, and please keep us infoirmed.
The most common pesky updates I get are Adobe Reader and Flash!
As an aside, sometimes it is useful to disconnect from the Internet when working on a large (or important) project - just to avoid automatic updates while working.
