Marco, just tried opening it up under a diffetent user. Same error message. Family Tree maker 2012 was not proprly closed the last time it was used. You may need to compact your last opened file to reslove any issues caused by improper shutdown. To compact the file choose "Compact File" from tools menu........only difference now is when I click ok, another box pops up that says FTM 2012 has stopped working. This didnt come up on main account.
