1.I have saved 2 values in a cookie like this:
If Request.Cookies("LoginSettings") Is Nothing Then
            Response.Cookies("LoginSettings")("DB") = rbDatabases.SelectedItem.Value
            Response.Cookies("LoginSettings")("Language") = rbLan.SelectedItem.Value
            Response.Cookies("LoginSettings").Expires = DateTime.Now.AddDays(7)
        End If

2. I go to my cookie folder and I see the cookie values:
   LoginSettings DB=SQL&Language=English localhost\<bunch of numbers here>

3. Want to read them back:
 If Not Page.IsPostBack Then
            If Request.Cookies("LoginSettings") IsNot Nothing Then
                If Request.Cookies("LoginSettings")("DB") IsNot Nothing Then
                   rbSystems.SelectedItem.Value = Request.Cookies("LoginSettings")("DB")  ****This line returns null***
                End If
                If Request.Cookies("LoginSettings")("Language") IsNot Nothing Then
                    rbLan.SelectedItem.Value = Request.Cookies("Language").Value.ToString

                End If

            End If
        End If


***But I keep getting Null Error on rbSystems.SelectedItem.Value = Request.Cookies("LoginSettings")("DB").
what am i missing?

Try something like this......

If Request.Cookies("LoginSettings") Is Nothing Then
dim cookie as new httpcookie("LoginSetting")
cookie.values("DB") = rbDatabases.SelectedItem.Value
            cookie.values("Language") = rbLan.SelectedItem.Value
            cookie.values.Expires = DateTime.Now.AddDays(7)
Response.AppendCookie(cookie)
else
dim cookie as httpcookie = request.cookies("LoginSetting")
cookie.values("DB") = rbDatabases.SelectedItem.Value
            cookie.values("Language") = rbLan.SelectedItem.Value
            cookie.values.Expires = DateTime.Now.AddDays(7)
Response.AppendCookie(cookie)

        End If

If the Request.Cookies("LoginSettings") Is Nothing shouldn't the Response.AppendCookie(cookie) line be Response.Cookies.add(cookie)?

Not sure.  I've always understood it that you append to something that exists and add something that's new.  Using that logic, if Request.Cookies("LoginSettings") Is Nothing there's nothing to append too?
