Ok. Here's something you could try. Go to his shared folder in windows(C:\Documents & settings\martin\shared). Create a shortcut on his desktop for that folder.
Open LW and go to the library page. Click on the folder that has all the files that need arrranged. Hi-lite the files and drag & drop them onto the shortcut you made.
When it's done go to the library page in LW and click the refresh button. Now hopefully all the files will be in the proper place.
Another suggestion would be to delete the LW pref. folder while LW is closed. Points #2 & 3 in this thread:
