CreateObject("InternetExplorer.Application") getelementbyname after navigate to another page

This will work fine.

(VB.NET)

Dim InternetExplorer = CreateObject("InternetExplorer.Application")
With InternetExplorer
      .Visible = True
      .Navigate("www.test.com")
      .document.getElementsByName("value")(0).Value = "test"
end With

But if i navigate to another page and try to "getElementsByName" again, i will become this error "HRESULT: 0x800A01B6".

How can i fix it?

I am grateful for every suggestion.
