I had this problem a while ago, disabling the cache for the entire application solved my problem, just add these line to the Global.asax.cs file

        protected void Application_BeginRequest()
        {
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
            Response.Cache.SetNoStore();
        }

Hope this helps.
