Retroactive Userpoints Failing

I am trying to grant retroactive points for content (blogs/comments) that I imported/migrated over from Drupal 4.7 to Drupal 5.1.

I go to the retroactive area, change the value to YES, and click Submit.
I get a lot of errors like this:
user warning: Column count doesn't match value count at row 1 query: INSERT INTO userpoints VALUES (1, 0, 1175786511) in /home/<>/public_html/<>/includes/database.mysql.inc on line 172.

Its showing 20 of them, with the only difference being that the first number after VALUES increments from 1 to 20. (There are probably more errors, but it only lists 20.)

Thanks
