Problem when trying to install OSCommerce from AV

[VerityNS]

Every time I'm trying to rollout OSCommerce from the Application Vault, I'm getting the following errors

ERROR Up LevelUp Level

Unable to query: Unknown column 'Show_db_priv' in 'field list'

--------------------------------------------------------------------------------

0: /usr/local/psa/admin/plib/database_mysql.inc:2 psaerror(string "Unable to query: Unknown column 'Show_db_priv' in 'field list'")

It might be worth saying that I'm trying to install OSCommerce into a subdomain. Also, this domain is on a static IP and not a shared virtual IP.

Any help anyone can give is GREATLY appreciated!
