Good Morning Agambitta,
You are are asking a very good question, which we as realtors can not answer, first and foremost because we are not attorney, and second we do not have the documents you signed and were provided to even help guide you in the right direction to get the answer you need. You will want to gather all of the documentation and then place a call to a real estate attorney so that you may have a consultation to determine where you actually stand on this matter. With all the different things going on now with foreclosure and short sales, it is best to be in contact with an attorney that can get you the proper information from the closing agent as well as the lender that approved your short sale.
Good luck on getting the answers you seek and need, and hopfully this will be solved fully for you so that you move forward with nothing hanging over your head.
