MyEclipse提示An error has occurred的一个解决方法

我用的是MyEclipse2016 CI 0，很惭愧是破解版，今早升级了之后提示An error has occurred,see the log….
然后打开了该Log文件，在文件最后面找到了错误提示：

提示找不到注册信息，有可能是因为破解的关系，所以升级后找不到，找了好久没找到解决的办法，包括删除workSpace，使用Myeclipse -clean，删除安装目录下的configuration目录下所有文件等等都不管用，因为破解的过程比较麻烦，所以不想折腾，最后误打误撞，替换了configuration目录后错误消失了。

修复过程：

1.在另一台电脑或者虚拟机或者别人的可以正常使用的MyEclipse安装目录下复制configuration文件夹下的所有文件

2.删除自己的configuration文件夹，粘贴复制过来的configuration文件夹，删除其中的Log相关文件

3.修复完成，再次打开可能需要重新配置所有东西，之前的配置在删除文件夹时一并被删除掉了，和新装的一样
