Roland CX-24 problems.?

I just borrowed my uncles Roland CAMM-1 CX-24 cutter along with his software which is Flexisign 7.5 V4 which comes with the little password dongle which is called "Hasp4 USB 2.02". My problem so far is that my computer which is running Win 7 ultimate 64x which in turn is running a virtual XP prof SP3. Neither Win7 or XP can pick up this dongle and run flexisign, both say the device is installed and up to date but both fail loading flexisign saying it cant find the dongle. any ideas?
