Refresh IE Object Values To New Page (VBS Excel Macro)

My doubt it's at the final of the code when the condition If IE.Document.URL Like constantsValues.urlLoginData Then is true, it enter into a class an introduce the user and password from a login page AND then the page is REDIRECTED to another page SO when it goes out the IF CONDITION, the values that I had at the beginning in the IE Object are now DIFERENT because I'm now in a new page.

So that's why I put Application.Wait for 30 seconds, and then try to refresh the values of the IE object and get the new ones, but it always get the first values (the values of the login page :S) NO the new ones :S

How can I update the IE object to get the values of the actual page?

Code:
Private Sub runMacro_Click()
Dim constantsValues As CConstants
Set constantsValues = New CConstants
