我这次搞笑搞大了

昨天觉得对分类的概念不是很清楚，然后动手尝试创建分类，设置各种属性，设置完了以后，又创建了一个新的content type，把分类给应用了～～然后又在这个content type上创建了新的内容，好像有一点理解它的意思了～～睡了一觉醒来～～首页报错：

user warning: Got error 28 from storage engine query: SELECT n.nid, r.nid AS node_id, c.*, n.title FROM category c INNER JOIN category_node r ON c.cid = r.cid INNER JOIN category cn ON c.cnid = cn.cid INNER JOIN node n ON c.cid = n.nid INNER JOIN node cnn ON cn.cid = cnn.nid WHERE n.status = 1 AND r.nid = 53 ORDER BY cn.weight, cnn.title, c.weight, n.title in D:\apache_www\drupal51\includes\database.mysql.inc on line 172.

我以为是创建分类的问题，就把创建的分类、content type全部删除～～～
结果连版面都不对了，原来放在右边sidebar的导航，等区块全没了～～～

现在在任何一个页面下都会出现类似的错误～～～

user warning: Got error 28 from storage engine query: SELECT DISTINCT b.* FROM blocks b LEFT JOIN blocks_roles r ON b.module
= r.module AND b.delta = r.delta WHERE b.theme = 'wabi' AND b.status = 1 AND (r.rid IN (2) OR r.rid IS NULL) ORDER BY b.region,
b.weight, b.module in D:\apache_www\drupal51\includes\database.mysql.inc on line 172.

头痛中～～～～连登录窗口都没了～～
