Hmm. This is new:

This is on a project that I mixed down yesterday in Jamaica Plain, without errors. All I did was mute some midi clips that were unnecessary... so it appears to be something in the K update.
I'm rolling back to JP to check that I can mix-down in that version.
Bummer.
UPDATE: Mixdown succeeded in JP, as expected. I'll try re-installing K a bit later and try the mixdown again, when I have some time to experiment. Stay tuned.
I'm seeing much the same thing, but without the warning window. Izotope IRIS2 doesn't work at all, replacing synths is causing consistent lockup (the window greys out and then eventual crashes). I'm getting phone-home pop-ups from both Sonar and Izotope.
I'll second the request asking how to roll back a version...saving that, I can always restore from backup (three cheers for daily incremental backups).
In short: Sonar was bulletproof for me from launch day until now. Currently, Sonar isn't useable in this state. Ouch.
Are you using vst2 or 3? vst3 works fine here...I've had Iris2 for awhile but hadn't gotten round to installing it. I just did, to try and replicate the crashing issue. First, I rolled back to "J" land, then installed Iris2 and all the additional content, added Iris2 to a song I'm working with, which has over 100 tracks of audio, synths, kontakt/falcon/omnisphere2 tracks, lot of Albion One... a song already beginning to stress my pretty robust system.
I verified Iris worked fine...at least the vst3 version...I use vst3 whereever possible, and also wanted to test the bakers new vst3 code. Iris itself was kinda boring but.... I saved the song, and reupdated to "K" land. Brought up the song with the iris track... played fine. Added another vst3 instance of iris.... recorded/played back fine...
Don't know if you're using vst3, but from here it works fine.
FWIW, if ur using vst2, try vst3.
If you're crashing, hope you sent in the crash reports for trouble shooting. The diversity of wintel machines is a real challenge and that's why it's
REALLY HELPFUL IF YOU POST YOUR SYSTEM SPECS, LIKE MOST OF US DO IN OUR SIG...
