Problem with Cossacks 2

[Northstar]

I have a problem with the patch... I installed the game and the protection, used the removal tool, ran the updater but then can't patch the sfdrv01.sys because it isn't in my c:/windows/system32/drivers path... It simply isn't there, so I can't patch it. When I try starting the game it does run the protection tool however. Anyone has an idea? I am using 2 harddisks and windows XP professional SP2. The windows-file on my primary harddisk doesn't even have a system32 file in it, the one on my secondary harddisk has one but without the sfdrv01.sys file in it. Any help would be appreciated greatly.
