Try to copy ntfs.sys and ntoskrnl.exe from Windows XP into /var/lib/captive.
The drivers from Windows 2000 cause problems, see

When I was trying to mount NTFS with the drivers from Windows 2000 (Knoppix 3.4 c't Edition), I got the following message.

Captive[1942]: sandbox: FATAL: file signal.c: line 203 (sigaction_SIGSEGV): assertion failed: (reg_eip_aligned!=NULL)

After copying ntfs.sys and ntoskrnl.exe from a Windows XP installation, the message was gone.
