Check when creating a new sequence that you have AVCHD, HDV and XDCAM presets available as choices. If that is not the case, your version has returned to trial mode and you need to deactivate, uninstall, run Clean Script CS4 2 or 3 times, reinstall, activate and update. (Deactivation and activation may not be necessary, but I advise it to be safe.)
I have asked support and they said it would take a few days for them to work on this issue.
And in less than an hour, Harm probably has the answer. Why this happens is still a mystery, but it has happened to many others. Harm's suggestions are the "fix," for when it does happen. Luckily, few encounter this, but enough do, to be worrisome. I'd love to find out what the contributing factors are to cause this behavior. Then, we could post a "do not do that - instead, do this... " and save the users from having a problem. Unfortunately, we do not know what "that," and "this" are. Phases of the Moon?
That fixed my problem. It is strange that no one knows why this happens.
Probably just too many variables involved. It does not happen often, but often enough that we get maybe one issue, about every month. Considering the install-base, that is a very small segment (probably do not hear of the majority here), but when it hits, obviously it's pretty unnerving to the user.
There have been quite a few complaints about the latest crop of Adobe installers (other problems usually), so it might be some weakness there - or it could be system-specific, or maybe something else.
Luckily, most of the "regulars" here know what to recommend first, and it usually fixes things nicely.
Glad that Harm got you going and good luck. Maybe it will never happen with CS4.3 (if one comes), or CS5. It would be great to never see this "reversion to trial" problem again.
PS - was going to remind you to give Harm his "points," but you beat me to that.
