"General Failure" Crash When Saving!!!

What would cause Sonar to crash when I try to save the project?
I'm working on the biggest song to date. 50+ tracks, some Melodyne rendering and effects in both busses and FX rack.

Are there any common no-no's I could violating?

I tried opening a different project and was able to do a small edit, then save and close it successfully.

But when trying to save our current big project, I get the error message, "General Failure".

I'm just getting to the point where I sort of understand rendering and using Melodyne and Bouncing to Tracks. But Bouncing to Clips is still a mystery.

I'm botching something up, but I have no idea what it could be.
I know my description is vague, but if anyone could shed some light on this I'd be very grateful!

Thanks again!

Thanks Slyman,
Hopefully Sonar is crashing because I've made a mess of my Melodyned' clips, and once I've straightened them out, all will be fine.
Question: After using Region FX and moving things around with Melodyne, what do I do then? Is the Bouncing to either Tracks or Clips "Rendering"? (There's no actual command called "Render", right?) And you say you think the results are the same... which is what exactly?
Also, is there a way to tell what's been rendered and what has not?
My project is screwed until I figure this out. So, I super appreciate your words.
Peace
 

I've had this error happen and it's super frustrating. You could try "save a copy as..." in a different directory. Or if that doesn't work, export all tracks, with or without effects, so you at least have something saved if you can't do it the normal way.

The video I linked on your other thread explained all the steps with Melodyne and rendering them.
