Nuke to SMF

[sfinaki]

Καλημέρα σας,
Προσπαθώ να αλλάξω το φόρουμ του phpnuke σε smf και σε κάποιο σημείο, όσες φορές και αν προσπαθήσω, μου βγάζει αυτό το σφάλμα:

Code Select Expand

Converting group access permissions... Unsuccessful!
This query:
INSERT INTO `katse_nuke1`.smf_board_permissions
(ID_GROUP, ID_BOARD, permission)
VALUES
(112, 27, 'post_new'),
(112, 27, 'mark_notify'),
(112, 27, 'mark_any_notify'),

(112, 27, 'delete_any'),
(112, 27, 'report_any'),
(112, 27, 'send_topic'),
(112, 27, 'split_any');
Caused the error:

Duplicate entry '112-27-modify_own' for key 1

Ξέρει κάποιος να μου πει τι να κάνω?
Ευχαριστώ
