on toca race driver 3

[leleware]

OK, latest driver done, uninstallation done correctly, installed the reloaded version from daemon tools 4, installed the no-dvd patch, replaced the exe, patched.... 5 minutes and... all off ! my hardware is:
mb gygabite GA-8I915P Duo Pro
cpu p4 560 3.6 ghz non-overclocked with silenttower and 12" fan
ram kingston 2x512 mb ddr dual channel
vga ati sapphire 850xt non-overclocked
4x 250 gb hdd maxtor sata raid 1
dvdrw pioneer...
all with latest drivers and bios.
no problem with other games, starforce protected ones included...
this seams just a sort of protection error, like a dvd check or a ring0 check (now i've installed alchool latest version and daemon latest version, + zone alarm pro latest, so a lot of things on ring0). Could it be another copy protection inside the exe code ? somebody told me about the "fade" protection of codemasters.. in fact before running the game there's no starforce installed on my pc...
I REALLY WANT TO PLAY WITH THIS BEAUTIFUL GAME !!!
