I googled for that error and read a few threads. You could try a repair of the character_ table, e.g.:

C:\>mysql -u root 57dr1
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5 to server version: 4.0.12-nt

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> repair table character_ ;
