Check for the following:
1. Do you have this character, "~", inside any character field in that particular table?
2. Is your SET NULLDISPLAY set to the "~" as well.

If any the above is true, make sure you replace the "~" data and retry.

This is based on the current Upsizing code found in VFP8SP1 as noted.
* Use tilde rather than comma in case commas in char fields
#define BULK_INSERT_FIELD_DELIMITER ~

This is long shot but regardless, having a "~" inside a character field will make the final text file bad form. This is an example of a badformed text file.

*create table (tcTargetDbfFile) (fld1 i, fld2 l null, fld3 c(5) null, fld4 d)
*insert into test (fld1,fld2,fld3 ) values (1,.t.,null)
*insert into test (fld1,fld2,fld3 ) values (1,.t.,"~")
*insert into test (fld1,fld2,fld3 ) values (1,.t.,null)
*Final text file content:
1~1~~01/01/1900
1~1~~~01/01/1900 <-- the fdl3,record#2 data caused a bad STUFF().
1~T~~01/01/1900  <-- the .T. wasn't translated to 1 properly.
