parallel dongle not working with xp64

I have recently installed Quatrus on a PC running Windows XP64 and found a problem with my Parrallel Port Dongle.

When I run the 32bit version of Quatrus it finds the dongle without any problem but when I run the 64bit version it does not find the dongle.

I have downloaded the latest sentinal driver from safenet and that does not fix it.

All help would be appreciated.
