Thank you for posting this question. I ran my FTM file through another GED program and got 44 pages of errors. I like FTM enough that I am going to fix them by hand.. but I appreciate your bringing this to my attention.
Update February 21:
Now down to 10 pages most of which is custom facts that I need to fix or complete and people with first names only that I need to hunt down.
Most errors could have been lived with but there were three marriage records that were totally compromised. The worst one was where the daughter of my 2 great grand uncle on my mothers side ended up married to my 4th great grandfather on my father's side. Go figure. That didn't show up in FTM, I had to run it through a PAF file to find the error.
