You're right, there are other logs in the Event Viewer, but there is absolutely nothing in them--no logs, I mean. They are: ACS, Application, Internet Explorer, Media Center, Microsoft-Windows-Forwarding/Operational, Security, System, and then Windows Power Shell, but only the Application and System have logs in them.
I am trying to run it the way it was installed, by using the icon, as I've always done. However, this is the first time, since I've upgraded my computer parts and changed to Windows XP Media Center. I know what you're talking about, concerning running it with administrative priveleges, but I'm not sure that that applies to Windows XP. When I right-click on the icon, no such option appears, as it would in Windows 7.
The funny thing is that on my old computer setup, and using Windows XP Professional--and even on my laptop, using Windows 7, it works fine, but on this new computer setup with Windows XP Media Center, it's a no-go.
Thanks again, Alan, for trying to help.
