2007 Beta Outlook locks up at Splash Page

[Warren]

I've just installed the 2007 Office Prof. program. I can get all other
programs to function correctly, but when I attempt to open Outlook, the
program freezes at the spash page. The left hand side of the screen shows
the folders, but the right hand side remains blue and the splash page simply
hangs.

I thought with the first time around it may take a bit to open the program,
so I let it sit there overnight, but it didn't make any difference. I
reinstalled, rebooted, turned off McAfee and still can't get the program to
work.

I'm getting ready to delete it and go back to 2003.

Any ideas?

Thanks

Warren
