[Gramps-bugs] corruption

[Ben C. <ben...@ho...>]

I last used Gramps 3 years ago (probably from Ubuntu 9.10) and got a great PDF after many dozens of hours inputting data.
I also exported the GEDCOM file and now, when I reopen the GED file on a new computer (Ubuntu 12.04) there are missing records and mashed relationships.
For example, my own record was AWOL and my wife was married to my great-great-great-grandfather.
Any thoughts on how this happened or what I might be able to do about it?
Thanks in advance,
Ben
