If your EAD was based on a pending I-485 application, and your I-485 application has been denied; then it is not possible to extend your EAD application based on filing a motion to re-open the I-485.
You would need a new I-485 filed with a new I-765, and depending on the facts, this might not be possible in October 2008 or November 2008, and even if it is possible, it would take approximately 3 months for the new I-765 application to be approved, that is, 3 months from filing the new case before you get new EAD.
It is true that if USCIS approved your motion to re-open and re-instated your pending I-485, then you could obtain a new EAD based on that re-instated I-485 being pending.
Yours is definitely a complex situation, and you will want to retain a qualifed attorney in your area to advise you. Good luck.
I agree with the previous answer. Try to obtain your own attorney if you must.
Check with a lawyer in your locale to discuss more of the details.
Good luck to you.
