Carol,
Yes, I will agree it is very frustrating to have the program not work properly.
To compact the file before converting from FTM 2010 to FTM 2014 I finally did compact the file several times before it converted it fully. To compact look in the tool bar under Tools and in that find Compact File. Save before and after each compact. Also save a copy of your original file before you convert it to the new format. It took me three compact tries before it moved all my files to the new FTM 2014 format. I hope it works for you as well........Ron
