change drive(path) in windows 7

I use Mixvibes Pro on a W7 Home Premium platform.
I stored my music on drive D:. Now I've a new notebook (also with W7 HP). The DVD player is allocated to D:. I've made an extra partition on this new notebook and I was forced to choose E: for this partition.
You already guess my problem, if I want to use MV Pro 7 on this new PC all my music (3500 MP3s) are directed by MV to to D: drive.
How to deal with this problem?
