Registry setvalue error...help please

[Getox]

i got my app to read the info from the registry but trying to set/update the value of it wont work..
the code im using is

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim rk As Microsoft.Win32.RegistryKey

        rk = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Trelio Software\TBrowser")
        rk.SetValue("startpage", homepage.Text)
        rk.SetValue("searchpage", search.Text)
    End Sub

anyone know whats wrong? thanks



EDIT:
nevermind i had to make it open with write access by adding "True" at the end of the rk line
