Sorry to have to welcome you to the Crash Club.
My FTM 2008 crashes any time I try to add a Source. It initially let me add several Sources before crashing; then got progressively worse until I now can't add even 1 Source w/o the program crashing.
I've talked to tech support numerous times and even uploaded my data file to them for testing. They claim it doesn't crash for them, but I've got FTM 2008 installed on 2 different pcs here and it does the same on both.
I'm still using FTM v16 for now but am watching for postings on other potential programs. I did download a trial version of Roots Magic. It migrated my FTM v16 file but didn't bring over any details for the Sources; just the Source titles. So that won't work.
I hate to bail out on FTM as I've used them from the start, but I know I can't use v16 forever.
