Hey… damn I know I’m supposed to remember your name…
dang.
Hey 101,
You’ll find a lot of information on how to tackle and bring down Billie Jean here:
That’s where Eric Kiser consolidated a number of threads wherein Billie Jean was tackled.
On top of that, I would [ersonally avoid the abbreviation, as it has… questionable connotations. 
With regards to your question: while most everyone has trouble getting her to submit, the trouble manifests itself in many ways, some of which unique. The only thing I can suggest is: if you have trouble getting the slow workout done, try it at an even lower tempo. The slow workout runs at 65 bpm if I remember correctly. I started at 50 bpm – and only when I had that down consistently, I moved on to the slow workout.
