iTunes isn't connected to my tracks

The location of iTunes on my Windows 7 laptop is:

C:Users\Margie\Music/iTunes\iTunes media\album title

and it works great. But I also wanted iTunes to be on my xp.

So I downloaded all of my iTunes Media file onto a big flash drive. Then I plugged the flash drive into my Windows xp, placed the iTunes media folder on the xp's desktop. Then I looked for a Music folder and then iTunes--and I dragged and dropped the iTunes Media folder into that location.

However, it didn't work. iTunes doesn't recognize any of my music (I even uninstalled iTunes and all its buddies.) I then went looking for the music and found it (see below.) I don't see how I can recreate the same location on my xp system since that system doesn't have "Users" or "Margie" available in the C: drive. So, anyway, this is the current, incorrect location of my iTunes on my xp:

C:Documents and Settings\Administrator Documents\My Documents\My Music\iTunes\iTunes media\album title

Help, I know how to move folders, etc. but xp doesn't have the same names available for me to figure out how to arrange things in their appropriate location.

Thank you.
