No Audio From SONAR X3 Producer (Solved)

Suddenly I am receiving no headphone (or speaker) audio from Sonar Producer using my new Steinberg UR22 AI. I am getting audio through my PC however.  I thought it may have something to do with my adjusting the latency to a 128 Sample Buffer size.   I reset the thing to 512 samples.  Same issue!  I removed  the Steinberg UR22 AI with and replaced it with my old TASCAM US 122.  Still the same issue!  Console meters and, of course, the meters in the track view,  show audio activity but nothing coming through headphones.  All of the audio track volumes and gains are set properly. Nothing is solo'd or muted.   It's gotta be something  really easy but for the life of me I can't find out what it is. There is sure to be a "DOH" in this story somewhere   HELP!!!
The CA-2A Leveling Amplifier bundled with my SOnar X3 Producer was intentionally made to not work. It would have been nice to get some sort of message indicating that I had 27 miliseconds or so to register the thing or I would be subject to the wrath of the Kingdom.  As I recall I did attempt to re-register but was not able to use the registration code. The reason was reflected in the message suggesting it was already used.  That was when I had to re-install my Sonar X3 and the rest of the X3 Producer software that was bundled. I chalked up my inability to re-register the software to the fact that I had already registered it a years or so ago. Subsequently some powerful force in Cakewalk's Kingdom of Software Marketing,   this very day, inhibited the thing. Why?  Who knows for sure but the Kingdom stated it was because I hadn't registered the software. 
 
That aside ... I finally found out that the problem was attributable to a failed FX ... in particular the CA-2A Leveling Amplifier.  I went to the CA-2A and found that when I inhibited it, the audio came through splendidly; however, I was informed by a dialog box that the thing expired. I had to re-register it.  This was my third time attempting to do so!   Could it be my first registration a year ago was not recorded ... or that when I tried to re-register it  the swecond time (with the re-install of X3)  something got screwed up causing the old registration to be voided.  I don't know but it makes me wonder  what the hell went wrong! I have time to spare on useful actions; but, not time to waste on screw-ups  (mine or someone else's).  Perhaps someone might share their experience and let us  know if similar issues have been recognized by others in the forum.
