You can create more than one session only error cause is you are using some object which is not initialized. If the error causing on accessing session then befor accessing check whether it is present or not like bellow
if(Session["Roli"]!=null&&Session["Emri"]!=null)
{//Now access the session variable like
f2txtRoli.Text = Session["Roli"].ToString();
f2txtEmri.Text = Session["Emri"].ToString();
}
else
{
//do
}
