Sample tictactoe file not showing in messenger

The activity sdk that I downloaded comes with the tic-tac-toe sample application. The steps I followed are as follows -

1. I edited the msgrp2p.xml file to point to my local webserver. I placed this .xml file in C:\Program Files\MSN Messenger.
2. I then transferred the htm file and graphics to the local webserver.
3. The problem is that the "Actions" menu does not show any link to launch the sample application when I start the MSN Messenger.
4. Infact none of the menus show the "Start/Run" option.

Is there a step that I am missing out here Does the xml file have to be present on the machine of another contact with whom I am to play for the "Start/Run" link to be present in my MSN menu
