7.0修改SQL sa密码后报错

K3Cloud7.0，SQLSERVER2008.
修改了sa密码后，按照

1、cloud 安装目录：E:\Program Files (x86)\Kingdee\K3Cloud\ManageSite\App_Data下的Common.config 文件打开
2、 删除


DataCenterName="管理中心" DatabaseEntity="K3DBConfiger201310234721356"
DatabaseType="MS_SQL_Server" CreateTime="10/23/2013 10:50:29"
DbServerInstance="127.0.0.1" DbUser="sa" DbPassword="买伃习企买伃习企买伃习企"
Id="319a3947-96d6-48b6-ae38-b64437c95118" />

这一段

3、 重新 打开SERVERIP：8000 以及http://SERVERIP:8000/silverlight/cmc.aspx
4、重新注册 不要创建了，因为只是密码修改数据库未删

以上操作后，管理中心是ok的，但是登录的时候报错如下：
