Did Program update to PRO 2012 (not a full upgrade) and now cannot edit any designs!

[ftdesigns]

In Home Designer PRO 2012 - I did a program update to this program yesterday Jan 9th - NOT A COMPLETE UPGRADE. But now I cannot edit anything I created even yesterday morning with PRO 2012. This seems bizarre to me. I am not in a position to upgrade to the full Chief Architect and am very upset that I have 2 jobs I cannot complete because I merely did a program update which was a pop up I got when I accessed the program so many times I thought there may be bugs that had to be fixed in PRO 2012. Would re-installing 2012 from my original CD fix the problem? I never would have done this update if I knew it would STOP my design business!!
Any help would be appreciated.
