Thanks Naples, the problem is with the XP user.
I continued searching the net after I posted here and came up with something that worked.
In order to correct the iTunes invalid file library problem in Windows, then do the following if you have a default install of iTunes and have not customized your library location ....
1. Open your My Music folder (should be under your My Documents folder).
2. Open the iTunes folder.
3. Move the file, "iTunes 4 Music Library.itl" from that folder to the desktop.
4. Open iTunes. Your music library will be blank.
5. On the File Menu, select Add Folder to Library.
6. In the dialog box that opens, navigate to My Documents\My Music\Itunes\ and click on the iTunes Music folder, then click OK
iTunes will rebuild your music library. If everything works properly, you can delete the file that you moved to your desktop. You can also use the above steps to add music files in other locations on your computer.:
I think there is malware on board as well, what is winpup?
