openerp7.0安装数据库时报错

安装成功后，没有报错，在创建数据库时出现错误：

OpenERP Server Error
--------------------------------------------------------------------------------
Client Traceback (most recent call last):
  File "d:\Program Files\OpenERP 7.0\Server\server\openerp\addons\web\http.py", line 203, in dispatch
  File "d:\Program Files\OpenERP 7.0\Server\server\openerp\addons\web\controllers\main.py", line 769, in create
  File "d:\Program Files\OpenERP 7.0\Server\server\openerp\addons\web\session.py", line 31, in proxy_method
  File "d:\Program Files\OpenERP 7.0\Server\server\openerp\addons\web\session.py", line 98, in send


Server Access denied.

解决方法：Master password:的值不能修改
默认值为admin，改回去应该就能安装了
