Media Center and Music Match errors

Dear Community Members

I have a Inspiron 9400 OS version 5.1.2.2600. A favorite child of mine doodle sooo much that my laptop obtained viruses. I believe these viruses may have stole all the music (612 CDs) I personally downloaded. Labor intensive! These albums were on Music Match also and I didn't have a problem with Music Match until I recently clicked to have Music Match updated. It now gives me the message, "This application has failed to start because PX.dll was not found. Re-installing the application may fix this problem." How do I reinstall Music Match? I recently had all the viruses cleaned up, but I still get the message in Media Center "The album cannot be found. Please ensure the album is on your computer and available in the Media Library."

 

When I had Music Match functioning the Media Center still gave that above message. When I go into Media Center the list still indicates that there are 612 albums in the Media Library.

 

How do I get these two problems solved?

 

Sincerely

Deep One
