用AMOS把图形路径都画出来了，数据库也选好填进去了，前面的步骤都没有问题，但是在运行的时候连续弹出以下四个对话框：

“An error occurred while checking for missing data in the group,Group number 1.

An error occurred while attempting to read the file,E:\amos.sav.”

“An error occurred while attempting to fit the saturated model for group,Group number 1.It will not be possible to compute the chi square statistic.

An error occurred while attempting to read the file,E:\amos.sav.”

“An error occurred while attempting to fit the independence model for group,Group number 1.It will not be possible to compute fit measures that require a 'beseline' model.

An error occurred while attempting to read the file,E:\amos.sav.”

“An error occurred while attempting to fit the model.

An error occurred while attempting to read the file,E:\amos.sav.”

然后无法计算。

综合上面的提示，个人愚见是读取的E:\amos.sav时出现的问题，但具体是什么问题不清楚。是软件问题还是数据库问题呢？

麻烦哪位大侠帮忙看看，不胜感激！～

PS：读取该数据库时，显示的N=680，但实际这个数据库是N=620。我尝试了读取其他数据库，N处都没有错误，于是将此数据库与没有问题的数据库各项对比核查，均为发现差别。不知道这里的问题有没有影响？
