Program Launch With USB

Hi

I have this program which will not open unless the USB that came with it is plugged in. Once the program is launched it will still run even if i take out the USB.

It's similar to those old CD games that wouldn't run unless the CD was inserted.

Problem is the computer besides for installing the drivers, the computer can't see the USB device and can't view the files on it.


Any help would be much appreciated.


Thanks
