Hi, the program is giving me a choice: I wait or I close and I lose...Is there a way to close but don't lose.  I was working on a project since maybe 2 hours and I didn't save...putting a plugin here and there and fix things here and there, I put the volume at maximum and i loved it.  but there was not a limiter on the mas ter so just after I did it...TADA!!!!  It freeze...On no...no...why did I forgot to save...please, if somebody know how to get out of there with the minimum of lost...tell me how please...

Just let it sit. Sometimes it takes a long time to save itself, but it eventually save itself. 

Thank's Grem!  But I saw your answer too late.  I had already closed the thing.  I'll know for the next time if it happen again that I get to much invalve in the creative way and lost the foot on the earth LOL.  I remember, a long time ago but I don't remember witch verson of Sonar, I had the same thing hapened but the program had create by is own a recovery file...anyway, it's a good lesson and I remember all the work I did but, this time, I'llbe more conservative...
 

I have been down that road so many times that I now have Sonar set to save every 20 changes. Not all that recent, but I may I only loose 5 minutes of time. 

Yes, but, this could be inverse.  You save it when you don't want to have saved...I wonder how that recovery file was made few years ago...
Thank's Grem

Turn on AUTOSAVE!!! 

Back in the day autosave was a source of problems. It's come a long way though I must admit!!

You could turn on versioning and auto-save?

That way you'd have the best of both, auto saves for peace of mind, and if it was a bad save you'd have the last versions to go back to.

Just make it a habit to click SAVE after any major edit or take. 

I don't use auto save so I have to remember to click on the save icon. 

Then, if you have an issue that results in a crash, you don't lose hours of work... maybe just a few minutes or the last edit or two. This happened to me the other day... working on pitch correction in melodyne..... and I always save at the end of every verse or chorus in melodyne. I hit something else in the program and it went to that little spinning icon... and sat there..... and sat there...... 

I had to stop the process to get it out.... and once that happens I know enough to do a complete from the cold start reboot to both the computer and the interface. 

Upon the reboot, and opening X1 and the project... I was back up and running and all of the data I had edited up to the last save... one minute before the glitch... was on the screen ready for me to finish the vocal editing. 

Yep +100 for saving regularly. Nothing worse than losing hours worth of work. I dont think X1/X2 are stable enough to do otherwise, mind you, neither is any other software IMHO
