Well, my headaches continue. I've done 3 system restores to different dates and now Sonar won't open any projects. I've reset VSTs and rescanned as well. I can't roll back either. When I try, CCC tells me
"Setup has detected that your application is currently running. Please close all instances of it now, then click OK to exit."
There are no instances of sonar running in task manager. I've rebooted and tried to roll back several times with no luck. Sort of stuck on ver 10 after 1 successful roll back from ver 11. All the problems started after I updated to ver 11 in the first place. My faderport also craps out (no memory etc...I have 16 gigs!) Version 10 was rock solid before this last update (as were all the other updates since splat came out) At least I'm not alone in my misery but that's not much comfort. Hopefully there will be a magic patch and we can all get back to making music soon.
