VB.Net 2008 Using Google Maps

[Auguy]

When I use Google maps with a WebBrowser inside of a Windows form the map displays but I get the error in the attached image. If I start the web browser of the computer everything works fine. I had it working with FireFox at one time but I must have changed a setting in FireFox. Am I doing something wrong here? Here is the code

      queryAddress.Append("[URL unfurl="true"]http://maps.google.com/maps?q=")[/URL]

StreetSum = (txtStreetNbr.Text.Trim + " " + txtStreetName.Text.Trim).Trim

' build street part of query string
If StreetSum.Trim <> String.Empty Then
  street = StreetSum.Replace(" ", "+")
  queryAddress.Append(street + "," & "+")
 End If

' build city part of query string
If txtCity.Text.Trim <> String.Empty Then
  city = txtCity.Text.Trim.Replace(" ", "+")
  queryAddress.Append(city + "," & "+")
End If

' build state part of query string
If txtStateCode.Text.Trim <> String.Empty Then
  state = txtStateCode.Text.Trim.Replace(" ", "+")
  queryAddress.Append(state + "," & "+")
End If

' build zip code part of query string
If txtZip.Text.Trim <> String.Empty Then
  zip = txtZip.Text.Trim
  queryAddress.Append(zip)
End If

' pass the url with the query string to web browser control
WebBrowser1.Navigate(queryAddress.ToString())

' OR 

' Direct call to Computer's Web Browser
System.Diagnostics.Process.Start(queryAddress.ToString())
