Can a bank foreclose on a home a year after it's been sold

We had a bankruptcy in 2005, signed an affirmation agreement on the 2nd mortgage, and also signed the paperwork to rescind it within 60 days of the BC hearing with the bankruptcy attorney.

We then sold our house a year and a half ago now, and the title company had us repay the primary lender out of the sale proceeds, but not the 2nd mortgage company, because the debt was supposedly discharged. So life went on..

Now, a few weeks ago we get a letter from the ole 2nd lender saying they are foreclosing on the home we sold in 60 days. They filed with our county, and a real estate friend also called me to see what the hell was going on, and wondering how this was possible. We no longer own the property... is this possible to be foreclosed on a house you no longer own after the title's been transferred?
