This is a special ddefine download site. If you're using an older version of 5.0 or downloaded filePro 5.0.10 on or before March 12th, 2003 you will need to download and install this new 5.0.10a version of ddefine replacing the 5.0.10 version if it. This download fixes a bug where a particular sequence of adding fields to a file could cause the file to become corrupted when the restructuring takes place.
