>>The script file it generated was missing key elements, which caused it to fail.

Just a guess here, but make sure your table has a Primary Key Defined. If a PK does not exist, the DataClas scripts will not work.

Make sure you have a PK set and re-run the script wizard, and then play the scripts against the database. Things should work correctly...

One other point, make sure your PK is integer-based and is also flagged as an identity column...
