卸载勋章中心6.1出现错误。怎么办，不要紧看好：

登陆PhpMyAdmin：

执行如下语句：
Drop TABLE IF EXISTS cdb_membermedal;
Drop TABLE IF EXISTS cdb_memberprice;
Delete FROM cdb_crons Where filename='medalcenter.inc.php';

这样就成功了
OK了，想重新装的话，只要在浏览器中输入：http://yourURL/ mc_install.php即可

===========
附：卸载后升级数据库方法，不想升级可不执行
Drop TABLE IF EXISTS cdb_membermedal;
