I'm sorry - I didn't make myself clear about the bobbin. What I should have said was it seems like the thread is coming off the bobbin in the wrong direction. Instead of from the top it is coming from the bottom of the bobbin or vice versa depending on your machine instructions.
If you look at your bobbin like a clock face, the thread end should be at the right of the bobbin at 12:00 position. If it is upside down the thread end would be at the 6:00 position. I know, clear as mud.
