Hi Clay,
Please follow these steps to set the MSN site as your home page:
1. On the address bar, type http://my.msn.com
2. Once the web site loads, click the word 'Home' under the House icon, then click on 'Set the Home Page'
3. A small window should appear in the middle of the screen, make sure that the entry is http://my.msn.com/ then click OK.
4. Sign out then sign back in to MSN to test.
If the issue persists, please reply to this post so that we could provide you with additional steps.
Hope this helps,
