Libraries - Restore Default

Just a quick note on this - I have an issue where I thought that my Libraries were missing, and the first two steps above did not fix the problem. I was about to perform the repair install, when I discovered the the libraries weren't actually missing. They were just hidden!

If you are having this specific issue, you can delete the (hidden) libraries, THEN restore the default libraries. It worked for me.

I appeared to have a little glitch. Could have been caused by all my fussing around trying to get the Media Center to properly get folders added (still working on that). Suddenly, my libraries had nothing in them and no access to them.

I navigated to the folder where the libraries are held:

file:///C:/Users/%username%/AppData/Roaming/Microsoft/Windows/Libraries

For each library listed:

Permissions - Allow or Deny Users and Groups

1) right click on it and select properties
2) go to security tab and see if your user name is listed in the top window (mine was NOT)
3) Click the Edit button
4) Click the Add button
5) In the object names box, enter your user name and then click Check Names, click OK once found and validated
6) Click on your name in the top list of Group or user names
7) Select in the Permissions window the "Full Control" option, then Apply

Repeat for each folder.

This worked for me where nothing else above did.

I've gotton a virus that I was able to delete, but it deleted almost 9,000 songs out of Windows Media Player, and the folders. I have to start over and rebuild my library. I want to put my songs back in the Music Library, but the defaults do not show, and I cannot restore them. What can I do?

I was able to recover the music I lost by restoring media player to an earlier date. NOW, media player will not stop updating media library. When I close out of media player and reopen it, it starts updating again, and will freeze up. I have read instructions about going to Tools, options, library and unchecking retrieve additional information from the internet. Doesn't help.
I tried to use the code entered into search at the start menu for clearing out media player and letting the system rebuild it, but my computer says the code isn't found. When Media Player updates, it freezes media player, and I get 'not responding'. It's frustrating. I tried Itunes, but I HATE it already.
I think I'm screwed. I don't know what else to do to make media player run the way it did.
HELP! PLEASE!
