I was deleting UAD plugins (I had a stoopid amount of them in the bin to see how far I could stack FX) when I crashed SONAR Platinum.  So I would say that you have to be cautious when deleting the UAD plugins while playing back a track.

The only thing I would be worried about it turning on and off the UAD plugs while it is playing so I have an instant comparision.  I assume this is not a problem.  (The problem, if there is one, on inserting or removing the plug completely, not turning it on or off.)

My one time problem has disappeared but I was referencing inserting or deleting plugs in the FX rack while the project was playing and not turning it on and off or editing any of them knobs of the plug while audio was playing. So hopefully, this was a false alarm.

How about changing the thread title to something not quite so alarmist as you're the only one of us so far who's experinced this issue.

Yeah, like "I did have a one time UAD error, not now"

Mr. Anderton,
 
I did try your VINTAGE ECHO FX preset and I did like how it sounded but perhaps too good for the vintage vibe but definitely great for some RETRO PROG music.
 
Keep em coming.

And the true test...too much feedback to create 50s sci-fi music.
 
I usually turn the head wear and wow controls up pretty far,

Some UAD effects are MUCH more power-hungry than others. Granted they're on a separate hardware card, but still...wonder if that makes any difference. Guess I'll give it a try.
 

BAPU, I actually tried to change the title by adding "False Alarm" to the end of it.... the forum software wacked out by SAFARI session by SAFARI losing focus instantly and I couldn't click on any control. 
 
I will try again now and see if it happens, for perhaps this was a ONE UP only issue as well.

PS - (edit) of course it worked this time
