hmm. i dunno man. Thats just what worked for me. Id recommend maybe just saving all your Projects to an external hard drive or thumb drive whatever. Nuke it then reinstall.

Hi guys - 
 
Well, I tried a couple of things and wouldn't you know it - I'm back online.  Here's what I did: having looked at a non-working track for WAY too long, I decided to create a new audio track and copy the wav form to the new track.  Ta-dah.  Once I updated the signal path and added TH2 into the effects mix I was right back in the game.  I had to delete any non-working tracks and place the accompanying wav files in new tracks.  Next I did the same for AD2.  It worked.  I guess I just hadn't given it that one final long, blank stare.  Any ideas about how this happened?  I can only assume it was related to my move to a new machine.  By the way, I tried to add my computer to my account at XLN Audio and what a pain that was, let me tell you.  No documentation specific to adding a computer to an existing account.  Trial and error (and a few colorful phrases) seemed to do the trick.
 
I did end up reinstalling AD2 after all this to ensure I had a clean install with the right registry options in place.
 
Thanks for sticking with me through this - you both introduced a couple of angles that surely helped me track this down to resolution.
 
By the way...in my endless crawling of posts, I found one from a couple of years ago (I think) that was related to latency issues.  The solution (which Anderton brought up) was to disable the High Definition Audio Controller.  I can't believe hoe much more responsive my keyboard actions and metering are!!!!  Just wanted to pass this along.
 
Thanks again.

sweet man i actually was trying to fix that my keys were taking too long to respond to hits lol. Im glad you got it worked out, sometimes it just takes staring at ur screen for hours to let it hit ya what needs to be done. Sometimes transfering computers can frustrating and annoying. Sometimes files just dont seem to like the transfer, thats probably what happened. Somewhere in the computer world it just didn't like it lol.  As for the AD2 i never went thru a process i just reinstalled like normal and put in the registration. worked like a charm lol.

 Yeah, I may never know what happened - all that matters is being back up and running.  Loving Sonar once again.
