Need Help with Browsers in VB.Net

I am a total Beginners and just trying to create a simple progamme.

I want the user to click a button which will open a web page within the forum.I used the following code

Private Sub RPRulesToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles RPRulesToolStripMenuItem.Click
WebBrowser.Visible = True
WebBrowser.Navigate("http://ucwonline.freeforums.org/")
End Sub

However when I run the Programme,all I get is a black screen in the VB.Net Browser.No text,nothing.Other sites such as Google and youtube seems to work perfect but not this one (It works perfect in the normal Browser)..Anyone has some suggestions or workarounds? I want to display the text from the site or the whole page but within the form without using any external browser.

Thanks!!
