wiglie on "Update preventing me from accessing admin board"

Hi, i'm working for this lady in France, she asked me to fix her website :

http://www.ali-provence.com

i tried to log in to the admin page and received the following error :

WordPress database error: [UPDATE command denied to user 'aliprovemmxi'@'10.0.75.69' for table 'wp_options']
UPDATE <code>wp_options</code> SET <code>option_value</code> = '1' WHERE <code>option_name</code> = 'link_manager_enabled'

WordPress database error: [UPDATE command denied to user 'aliprovemmxi'@'10.0.75.69' for table 'wp_options']
UPDATE <code>wp_options</code> SET <code>option_value</code> = '25824' WHERE <code>option_name</code> = 'db_version'

WordPress database error: [INSERT,UPDATE command denied to user 'aliprovemmxi'@'10.0.75.69' for table 'wp_options']
INSERT INTO <code>wp_options</code> (<code>option_name</code>, <code>option_value</code>, <code>autoload</code>) VALUES ('db_upgraded', '1', 'yes') ON DUPLICATE KEY UPDATE <code>option_name</code> = VALUES(<code>option_name</code>), <code>option_value</code> = VALUES(<code>option_value</code>), <code>autoload</code> = VALUES(<code>autoload</code>)

Mise à jour terminée

La base de données de WordPress a bien été mise à jour !

Is there a way to fix this, easily or should i tell her that i can't help her ?

Thanks in advance :)
David.
