Hallmark card studio 2010 has encountered a problem and needs to close

Hi, I have some issues with using Hallmark Card Studio 2011. While I’m in the middle of making a card I encountered this error message all of a sudden stating “Hallmark Card Studio 2011 has encountered a problem and needs to close. We are sorry for inconvenience. If you are in the middle of something the information you are working on may be lost.” After this occurrence, all of my work is lost even though I have been manually saving my project. Could someone please help me with my problem? Thank you in advance.
