I wanted to let you all know that the machine is "fixed". I did file a complaint with EBay because the seller didn't contact me. He called within the hour after posting, guided my DH on how to take out and insert the machine and voila' the machine sews.
Thank you all so very much for all your great suggestions. I feel really stupid not to have figured this out for myself but it's where I am in life I guess, dumber then a plank.
