Pro line Baby Lock timing

Question

After reading your posts, I believe I need to adjust my timing. I have a Baby Lock ProLine BL 5000n. Sweet machine. It won't pick up the bobbin thread. I've tried multiple rethreadings, bobbin changes, new needles and (gasp) even reading the manual. I did break a needle at the end of my last sucessful sewing session - so I'm pretty confident that it's the timing (said the rookie).I would like to learn how to adjust the timing. Help Please!
