Can't seem to create a new user account

[David Schwartz]

I'm trying to create a new user account. I've tried several ways but they don't seem to work.

1) CREATE USER 'mensch' IDENTIFIED BY 'justice';
>>ERROR 1396 (HY000): Operation CREATE USER failed for 'mensch'@'%'

2) CREATE USER 'mensch'@'localhost' IDENTIFIED BY 'justice';
>> ERROR 1396 (HY000): Operation CREATE USER failed for 'mensch'@'localhost'

3) INSERT INTO user (Host,User,Password) VALUES('localhost','mensch',PASSWORD('justice'));
>>ERROR 1146 (42S02): Table 'jcc.user' doesn't exist

It appears that there is no user table but there is a users table so I tried the following:

4) INSERT INTO users (Host,User,Password) VALUES('localhost','mensch',PASSWORD('justice'));
>>ERROR 1054 (42S22): Unknown column 'Host' in 'field list'

Here's what the users table looks like:

mysql> describe jcc.users;
+-----------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+------------------+------+-----+---------+----------------+
| uid | int(10) unsigned | NO | PRI | NULL | auto_increment |
| name | varchar(60) | NO | UNI | | |
| pass | varchar(32) | NO | | | |
| mail | varchar(64) | YES | MUL | | |
| mode | tinyint(4) | NO | | 0 | |
| sort | tinyint(4) | YES | | 0 | |
| threshold | tinyint(4) | YES | | 0 | |
| theme | varchar(255) | NO | | | |
| signature | varchar(255) | NO | | | |
| created | int(11) | NO | MUL | 0 | |
| access | int(11) | NO | MUL | 0 | |
| login | int(11) | NO | | 0 | |
| status | tinyint(4) | NO | | 0 | |
| timezone | varchar(8) | YES | | NULL | |
| language | varchar(12) | NO | | | |
| picture | varchar(255) | NO | | | |
| init | varchar(64) | YES | | | |
| data | longtext | YES | | NULL | |
+-----------+------------------+------+-----+---------+----------------+

Any ideas about what might be going on would be greatly appreciated!

TIA,
