When trying to restore data from backup file I get the following error:

Importing lsql_Links ... (starting at line 924 of /home/avispanet/links.txt)
Starting import to table lsql_Links ...
A fatal error has occured:

execute called with 23 bind variables when 17 are needed at /home/www/website/cgi-bin/links/admin/Links/Import/BKS2.pm line 167, chunk 924.
Please enable debugging in setup for more details.

Apparently some files are not automaticaly updated when aditional columns are added in links table. Six (6) columns/variables were added and the backup data file contains their info when it was created/exported. Any idea how can I restore the backup file without any errors?
