You might try using the System Restore Utility in Windows, it resets everything on the drive to a previous date/time.

Start/All Programs/Accessories/System Tools/System Restore

Completely safe and undo-able.

I've tried that and unfortunately I don't have a restore point at time where the file would be in its previous state -_-

Perhaps I should try it on another computer before I go conclusion jumping? See if the problem lies within the project itself.

I'm stumped....I've had projects get corrupted in earlier version of Sonar, but not to the point of no playback. How frequently are you set up to autosave? 10 or 15 minutes is a good idea, you'll never lose more than that much work if something goes nuts on you. Have you asked for help on the Sonar Forum at Cakewalk's site?

That would seem the logical place to go yet I haven't gone there. I'll make a thread and see what responses I get. Thanks!

BTW, have you looked in the primary Project folder for an autosave of the .cwp file? You might get lucky.

I save a quick .wav to my SD card to play through another medium to check my mixing, saved one last time, and closed down Sonar

Saved it where? What kind of soundcard are you using?

I saved the project file to the Cakewalk project folder, as I usually do. The souncard is whatever came with the computer.

So it isn't set to "loop" with back-to-back start and end points right?

Can you play a project of a comparable size and have it work correctly and THEN open this project in question and it still doesn't play?

I've opened one nearly as big and had it work well and then tried this one to no avail. It isn't set to loop at any point, just play through and stop.

If you do not have this app, get it and run it.
Take a walk down memory lane:

The link goes to the Cakewalk Audio Finder tool. If there are any issues with associated files with this project, this tool should be able to identify some of these concerns.

As a note of caution, if you do not have a regular back-up routine for recording projects already in place, this is almost exactly the correct time to start one.

The correct time would be before you begin the project, but maybe it isn't too late.

Let us know what you find,

Space,

Is this going to work with S6 or S7? The link only lists S1 through S5. Thanks for the heads up though, I still use S3 along with S6 and was unaware of this.

It is backwards compatible to SONAR 1.

I want to ask why do you do this, run multiple versions, but I'm afraid you might answer:)

Your fears are come to pass! I use w2k for my OS and plan on sticking with it as ong as possible. There's a bunch of reauthorization hassles with upgrading to XP I don't feel like dealing with, and I like w2k better than XP overall. When I upgraded to S5 and then S6, I was only able to save a .cwp file about 50% of the time, which gets frustrating. I called Cakewalk, but they don't offer S6 support run on w2k. One day I had an idea to create the project in S3 and then work on it in S6. Flawless. That's why :)

My fears are often unfounded.

And that is a good reason, because it works for you!

One reason the audio engine will stop is when you overload it - check to be sure your latency setting is the same. Also check to see if you might somehow have an invalid plugin, or a plugin that's become corrupt.

I would save a copy of the project to a new name just for testing, mute and/or remove each plugin one at a time and see if/when it starts playing again. Another thought - you wouldn't happen to have a file in the project loaded from a removable media would you? Just a guess, but that might cause problems since it isn't a fixed drive letter, and might be seen as more than just offline or unavailable media.
