Okay, so this may be a dumb question, but I just bought a new recording interface for my laptop and SONAR X1 LE by Cakewalk is the program that came with it. I am a guitarist mainly, but I also sing. I was recording two separate tracks; one guitar, the other vocals. Now that I am finished I want to combine the two so that both tracks will SAVE as one. I don't know how to do this though. The playback in SONAR plays both at once, but it will not save both tracks as one file. Can someone help me? 

Select everything first, then
File menu > Export > Audio
If you export it as a 16-bit WAV file, most media players will play it.

To add to Kev's, export will take your audio out of Sonar. If you want to combine all tracks and keep them in sonar, you will need to bounce it to a single stereo wave file.

Also, you don't have to select everything.  If nothing is selected, by default Sonar will export everything.

If you select nothing, no track will be exported. You have to select something in order for it to export. Try it and you'll see.

I've never selected anything when exporting a project. Selecting is necessary only when you don't want to export everything. No selection = select all when exporting is in question.
Muting the unwanted tracks is another thing.

Hi Emma,
here is a nice tutorial how to export multiple tracks as a single file.
