I fix it...and found the problem...I took out the black bobbin case and under it was a huge amount of lint. The link preveented the bobbin case to lay down correctly so that the thread was getting stuck on a metal piece preventing the thread to move...so glad I figured this out...Now I just have a pounding headache...but its fixed.
