哈尔滨残疾人保障金:关于PHP+MYSQL论坛的架设问题！

在论坛安装时提示：
Discuz! info: Can not connect to MySQL server

Time: 2006-4-19 3:23am
Script: /bbs/install.php

Error: Access denied for user: 'thslang@localhost' (Using password: YES)
Errno.: 1045

Similar error report has beed dispatched to administrator before.

这说的应该是：不能连接到MySQL 服务器
访问否认为用户: ' thslang@localhost ' (使用密码: 是)

但是空间服务商是提供给了我数据库名字的密码的，服务器提供商的邮件如下：
