When I push play, nothing happens in Sonar 7 Producer

Katnip

I'm using a Lenova laptop with Sonar 7 Producer for playback of backing tracks on gigs. I have the Cakewalk UA-25UX as an audio interface. Everything has worked fine until last weekend when it would no longer play the song when I pushed play.
 
I've done a searched to see if I can find the solution, with no success. Loop is not on. I can move to the end of the audio track, then back, or move the now time to any measure, it just won't play when I push play. I'm sure this is a simple fix, but I haven't found it. Any ideas?

Does this problem apply to all your Sonar projects or just one in particular?

Open Console View and look at Buses and Mains.  Is the Mains named "Cakewalk UA-25UX" (or something similar) and is the Master bus' output routed to this?

If the Now Time marker is not even moving, this most likely has nothing to do with routing or soundcard.

If no tracks or buses are routed to the soundcard, the Audio Engine will be off and the playback button will not respond.  Of course this may not be the cause of the problem in this case, but don't rule it out until we have more information.

First of all, thank you for all the responses. I'll run through here and anwer the question's posed in the responses:

I get the same behavour on all of the projects I open.

The Master Output Buss is correctly routed to the Cakewalk UA-25UX.

I've tried pushing play every which way: spacebar, clicking play with the
mouse.

A virus can be ruled out. This computer has never been connected to the Internet and the computer that I created the backing tracks on hasn't either. The only programs in either are music programs that I purchased from authorized dealers.

Let me offer a little more information.  I have never actually created a project on this computer other than to transfer a finished WAV file to it from my studio computer. I create all the track on a PC that runs Sonar 8. I simply set up a project templet that would play each of the backing tracks that I imported from the PC. Each project has only the one WAV file of one song. The laptop has no purpose other than to play the tracks on gigs. It has run perfectly up to this point, as has the PC with S8.
I guess since it happens on all of the projects it probably is a global problem, I've checked to see if the soundcard is working properly in the Control Panel, and it indicates that it is. Even when I move the Now Time marker to another location by clicking that location with the mouse, it still won't move when I click play. That's the only real problem that I'm trying to solve right now. I'll address the scrolling throught e playlist issue after I've fixed this.

Thanks agian for all the responses.

More information still:
I just went to the playlist function and after is scrolled through all of the songs it say: "This project contains some looped tracks which could not be completely expanded".

So, I think it's simply moving on to the next song because it can't move past the beginning, since somehow it's trying to loop from the same start and end point. I don't have the loop function on. However, (pardon me for not remembering the correct termonology)  the little green triangle at the top if the Now Time Marker appears on both sides of the Now Time Marker. This makes me suspect that it has been set to start and stop at the same location.

I just installed my version of Producer 8 to see if what might happen with that version and I'm having the same problem. This is getting weird. Everything seems to be set correctly. It's recognizing the audio interface.

Someone else did this - Under options - audio under the general tab. Playback timing master was set to -none- somehow, so I changed it to ASIO and everything was good to go again.
