I have a Sapphire 850. You should be able to sew with a partial bobbin. When you thread the bobbin, make sure you hear a "click" when you pull the thread through the threading slot, and that it's unwinding in the right direction.
There is a Yahoo group devoted to the Sapphire. They have lots of good advice.
