VBAdebugging工作正常，但运行时出错

我最近一直在为自己定制“网站爬虫”来制作一个网站索引/网站地图，自学自己的VBA。

所以我的代码（完成时）将查看并点击网站上的所有链接。

我能够从主页获得所有链接没有问题，并将其放置在Excel中。 但是，当我尝试从其他页面获取链接时，出现运行时错误，如：

“运行时错误'70'：权限被拒绝”

要么

“运行时错误'91'：对象variables或宽度块未设置”

但是，当我进入debugging模式，并进入代码，我不会遇到任何这些错误。 这很奇怪。

有一点要提到的是，我从一个有很多安全设置（包括互联网限制）的系统访问网站，这就是为什么我有这样一行： CreateObject("new:{D5E8041D-920F-45e9-B8FB-B1DEB82C6E5E}")而不是Create(internetExplorer)等…

它被困在我的代码下面的For Each tabLinks In ieLink2 。 我已经删除了链接，但希望每个人仍然可以得到这个想法..（请注意，我是新的StackOverflow，所以我不知道这是适当的，像这样发布整个代码，或者如果我应该只发布一块我的代码）。
