Quite often when I open an old 32 bit project created in X1 Exp. using Dimension LE, every instance of LE is grayed out and silent. I always have to delete the instruments and insert new ones.
 
What's going on with Dimension LE?

This can happen if you've frozen a synth and the audio is missing - not sure in your case though.

That may be it, but I never move or delete audio files.
 
Could frozen audio files just disappear over time OR are they tied to the Audio/Picture Cache folders?
 
P.S. As I write this response, all the text in your post has disappeared. I see this happen frequently as well.
Could it be I have this affect on things? I can also make street lights go out as I drive by them...

Maybe so. I just opened a 64 bit X2 project I saved yesterday and all the Dimension PRO synths are disabled.
 
More deleting and reinserting.
 
Most disconcerting!

For fun I closed the project and reopened it... and the Dimension tracks were enabled as they should be.
 
Something is wrong with the way Sonar loads in or maybe it failed the VST scan. We may never know.
