Ok, I adjusted all my empty VFP date values to be 30/12/1899 00:00:00. Now, I can have the package to understand that and import the records. But, I have an ancestral tree of martial arts masters in that table so we have birth date going up to the 14th century. So, one of my date is 01/01/1417 00:00:00. And, of course, the package cannot understand that as it is lower than 30/12/1899. What now?
