Hi Alex

                    {
                        try
                        {
                            if (!Chat.Contains(msg.From.Bare))
                            {
                                string nick = msg.From.Bare;
                                frmChat fm = new frmChat(msg.From, Xmpp, nick);
                                fm.Show();
                                fm.IncomingMessage(msg);
                            }
                            else
                                Chat.Remove(msg.From.Bare);
                        }
                        catch (Exception ex) { MessageBox.Show(ex.Message); }
                    }
                    else

as the error message sais you are adding an entry (key) to a collection which already exists.
This problem is not related to any MatriX code directly. So check code which Adds items to a collection.
