Sadly, that isn't one of the file extensions that 2012 will accept (the .fbc). If I try it from the .ftw instead, it says "Please compact the file by choosing "Compact File" from the "Tools" menu in the Family Tree Maker version where the file was last used and try importing again."

When I try that in 2005, it tells me it's too new a version for Family Tree Maker 2005 starter edition and can't be loaded. To upgrade, visit www.genealogy.com.
