License Migration

My son has just bought a new computer and transferred all of his music over from the old computer.

None of his music will play and he is getting Licence error messages. It is the same XP Media Center 2005 that he had on his old computer where the music played fine. He has downloaded the Microsoft drmwizard.exe but cannot get it to install. He gets the message

"this application failed to start because the DRMClien.dll was not found. Re-installing the application may fix this problem"

I have tried to istall the drmwizard.exe on my computer and I get the same message.

Can anyone help fix this license problem?

while reading the info on drm, i noticed this:

is it possible to transfer them manually?

also, is it possible that you don't have it enabled in windows media player?
and, finally, have you run all of the windows updates?
