Another way to free the file lock is to boot into safe mode. Set Explorer to show hidden and system files.

Delete the existing mcepg database and backup folder:
C:\ProgramData\Microsoft\eHome\mcepg2-0.db
C:\ProgramData\Microsoft\eHome\mcepg2-0

The version numbers might be different for you. Media Center rebuilds the files when you run the MC Setup.

Can you test media center's internet connection?

Tasks > General > Windows Media Center Setup > Set Up Internet Connection

If it fails, it might be this problem I had in Win7 beta that prevented me from downloading the EPG.

Can you check the media center logs in event viewer?

In the Start menu, type "event viewer"
Run the event viewer program
In the left panel, open "Application and Services Logs"
Then open "Media Center"
In the source column, look for events from "MCUpdate"

To test the manual EPG download:
In the Start menu, type "C:\Windows\ehome\mcupdate.exe -manual -nogc -p" then press enter.
In the notification tray you should see a new icon for the media center download.
In the event viewer, press F5 to update the event log. Hopefully, there is a new event. It might say something like:
Post the event log here and maybe we can figure out the problem.

It looks as if it isn't downloading the EPG listings. My event log has these entries for example:

4:50:05 PM - Retrieving EpgListings.
4:50:06 PM - Processing EpgListings.
4:50:06 PM - Retrieving EpgListing.enc.
4:50:10 PM - Extracting 28482520_ListingData.mxf.
4:50:12 PM - Processing 28482520_ListingData.mxf.
4:52:39 PM - Processing of EpgListings is complete.
4:54:20 PM - Update successful.

You said that there were no channels available for Live TV.
What was on the the Guide Listings? Did you have Internet TV?

I'm beginning to think that the EPG won't download if a TV tuner is not found. Is your TV tuner working? Have all the drivers been updated? You can check by typing "Device Manager" into the Start menu. Open, " Sound, Video and Game Controllers"

• Is the TV tuner listed?
• Is there an exclamation mark next to it?
• Double-click the device entry. In the General Tab, under device status, it should say that, "This device is working properly."
• In the Driver Tab, you can attempt to update the driver.

If you are sure that the hardware is working, and
you are willing, perhaps you could setup MC for my location so we can compare. I imagine you've done this a few times. Tasks > TV > TV Signal > Setup TV signal

• TV Setup
• United States
• 98226
• Download TV Setup Data
• Stop Examining TV Signals
• Configure TV Signal Manually
• TV Signal Type: Antenna
• TV Tuner Selection: Digital Antenna (ATSC)
• Enable Your tuner

or

• TV Tuner Selection: Analog Antenna
• Enable Your Tuner

You won't pick up any signals but it should allow you to download the EPG for Vancouver/Bellingham

I agree with Bob. 7MC doesn't seem to recognize the tuner. When you ran the TV Setup, and manually configured the tuner, did media center find the hardware?

Often HP uses proprietary hardware in their PCs. You might want to download the latest drivers for your tuner card from HP.

I thought you had a separate TV tuner card. But you keep talking about "video" card drivers. Does this mean that you have an ATI All-in-Wonder video card?
