Music2000 PC Edition

[The+Deleted]

So, after years of wondering how to get my M2000 tunes onto a PC I find a copy of the game availiable on eBay for the PC. Awesome, I think, and so begins a bitter price war until I absolutely pwn the feckers. However, it appears in my musical jizz bomb I under estimated just how compatible the programme would be with my PC, which runs the ever reliable Vista.
So, on trying the disc unsuccessfully on my laptop, (wouldn't register without DIRECTX7) I copy the files onto my mp3 player and transport the files to the PC, my disc drive still Out of Order.
So I DL directx7, which...ta-DAAAA- is not compatible with my OS. Brilliant!!"!!!
I have all the files on the PC but no way of using / installing the game!!!
Please, for the love of all that's good and holy, help me get this damn thing working.

I can upload the files for anyone to use if need be so you can work it from your end.
I cannot emphasise enough how keen Iam to get the twat up and running.

OK, is there any way to use an earlier version of Windows on Vista as there was with XP?
