Please Help Me Asap!!!!

I just bought my second toyota 9100 emb machine. I noticed that it was not cutting the thread very well, but was a minor problem. Of course now that I'm in the middle of a HUGE job that I need to have finished tomorrow afternoon that I NEED to make rent, its not cutting the thread at all. I need to know whats going wrong and how to fix it. Any help would be GREATLY appreciated. Thank you
