You are not screwed, these are empty threats to scare a settlement out of you. Don't spend any $, don't settle and don't waste $ on a lawyer. Most of these guys just split their fee with those who claim they will sue you. These don't go to trial so seriously don't stress about it. Change your contact info with Comcast or you will start getting calls once they release your info, and they will. Don't talk to them. Check out dietrolldie.com for folks in the same situation.
