When things don't work - always calm down and think before you do something stupid. Like when I got my new mill. Nothing worked. Could not get it to fire up. Was all ready to jump on the phone and explode. Calmed down, thought about it. I knew it had a lot of lock-outs, but missed the one on the chip sheild *click* all works now! Saved myself some embarrassment. Oops - now everyone knows. Shame.
