OK, this is totally weird, but here is what I found. The tracks' outputs were going to the correct busses, and both the tracks and the busses had meters lighting. The master bus was not lighting, so I started looking for why.
 
I noticed that all of my buss' outputs had changed to the wrong sound card channels. So, just change them back, right? Wrong. When I clicked on the outputs both in console and track view, the fly-out menu didn't do anything. It was as if I was clicking on a picture--no response.
 
I closed the project, but left X2 open. Then I opened the other project that I had sound from and double-checked the I/Os and played the track. Then I closed that project (leaving X2 open) and opened the project with the issues. Now, the outputs respond and I was able to select the correct sound card channels to route to the master bus.
 
I don't think I've ever dove for the save keys as fast in my life.
 
So it works, but what the heck? Maybe I did something that changed my buss' outputs, but why couldn't I change them back initially?
 
If it affected my other project, I would lean toward my sound card not being compatible with my new DAW--but the other track played.
 
Still, it might be a compatibility thing. It was as if there was only one output for X2 to choose, so the menu didn't open. I checked my audio settings in X2 and it was all good.
 
Really weird.
 
Thanks everyone for the input (pardon the pun).

Thats what I was suspecting happened. Thats why i suggested you look at your main outs.  

I have had this happen to me before on a couple of occasions. It would seem to do it when you move something around graphically such as resizing a track or opening a plug in window while audio is playing. I found that if you just do a save as and change the name (I added a number after the project name)and then close the project and reopen it, all was good. I am using onboard Intel video.

I can't be sure, but I think the audio was playing while I resized the tracks. The routing issue I can deal with--very minor. But not being able to change it because the buttons don't respond really concerns me.

I never noticed if it had changed the output channel when it happened but I would get the same behavior with the meters showing output on tracks and master bus,but nothing on main output meters.As I said I just saved and reopened the project and all was normal. I have no clue why it does this and actually have not had it happen lately.
