Try deleting the files in your workingdb folder and re-loading the roster you're working with.

ok working db in my documents / we know iight. ill be back

Andrew,

did not work for me i deleted it and it still wont let me create a player is there another way with out having to reinstall ?
i dont want to lose what i got saved.

If you reinstall the game you won't lose any saved files. However, it's probably not going to fix your problem anyway.

Have you made any changes to the appearance.dbf file?

yes i have i was adding players in from d league and missing players.
so i was in appreance and players dbf. andrew i got so mad i unistalled db commander but i can install it back.

If you were adding them through DBF editing, something's likely gone wrong which really could be about one of a million things. I'd suggest starting again from a backup.
