this is a new one, won't boot up, shut off machine four times and rebooted.  the program won't start up.  I have spend about 25 hours on it this fall at different times.  about six hours two weekends ago, so I don' t know what happened.  Advice?  Thanks 

just booted. I will check it as I work to see if anything else weird happens.  maybe I didn't wait long enough.  three times though the machine asked me to do diagnostics to no avail. Anyway, back in business.  Also, I appreciate you guys, I can't believe how dedicated you are to the rest of us.  Really quite a community.  Randy 

I would do a fresh install of Sonar to make sure everything is ok with it
