If you are having problems getting ReWaRD to communicate with the security key (aka 'dongle'), try downloading and installing the latest Aladdin HASP device drivers from:
http://www.aladdin.com/support/hasp/enduser.aspx
The Geocentrix CD (which is sent to all customers who take out technical support) also has the latest drivers on it, in the folders:
Setup\HASPHL (for the drivers) and Setup\HASP (for the Licence Manager)
