The error appears to relate to the macro trying and failing to open a second instance of IE. Try the following instead
Code:
Dim myIE As Object
Dim redURL As String
redURL = "http://www.gmayor.com/Word_pages.htm"
On Error Resume Next
Set myIE = GetObject(, "InternetExplorer.Application")
If Err Then
Set myIE = CreateObject("InternetExplorer.Application")
End If
On Error GoTo 0
myIE.Visible = True
myIE.Navigate redURL
Do While myIE.Busy
Loop
