Had a project playing and started red lining the first thread on the cpu. Closed the project and reopened and got an error message. Something to do with required data.  Now I get no sound and no cpu activity.  What did I do?

Did you reboot the computer? If you're still getting the error message after that, make sure you jot down the entire message and post it. If it's a Sonar or synth message, someone might know what it means. If it's a Windows message, you can google it and probably get some info.

Yeah I did a reboot. The error message disappeared before I could read the whole thing. But what I remember was  a Sonar message of  required data. The audio engine is on but no sound, no cpu.

try looking in preferences to make sure all your inputs and outputs didn't get whacked.
Also could check windows for the same thing.
This has happened to me before. Can't explain why, but it happened.
good luck
 

Forgot to ask, is it just that one project, or are you not getting any sound or CPU activity in any project now?

Do you get sound in other programs ?

Try your back-up. when ever you get an error message saying you do not have the required data, you shoudl try your back up

No sound from any programs. Just tried Windows media player. Tried a system restore, but that didn't work.
 Could it be something got screwed up with my interface?

Maybe try a different USB port. Hopefully your motherboard didn't get too hot and fry something (unlikely).

Well you guys got me thinking it was the computer and not Sonar. I powered the computer down completely for about ten minutes and started it back up.  Bam! I've got sound.  Don't know what happened, but it all started when I red lined the cpu. I'll have to watch this in the future. Thanks everybody for jogging my brain.
