Graphic problems with Grand Prix 3 and Windows 7

Hallo everyone,

I have two graphical problems since I've installed Gp3 (and patched v1.13) on Windows 7:

1) in hardware mode a purple rim on the wheels (seen in cockpit), I think it's something that has to do with 3d card settings, but I don't know precisely what:

2) so I've tried in software mode and the colors are totally messed up:

What can be the problem?

Thanks
Andrew

I forgot to write my specs:

Intel Core2Duo E8200
2 GB Ram
Nvidia Geforce 9600GT (ForceWare 190.62)
Windows 7 32bit

the purple rims can be fixed by opening the tyre bmps in paint, and painting the pink areas black/grey
