Update date changed???? Please help!!!

I just saw that all my family members' I-485 were updated today. Is there anything to be worried about? My lawyer sent a letter to us and said he would not represent us any more after I was laid-off from my sponsored company. I don't have a job yet. Any suggestions? By the way, can my previous company continue to sponsor me even if I do not work for it? Thanks for your kind inputs!
