Charlie you are a complete star! i changed the compat mode and it worked first time i think i love you really!!!!sorry just read the last part of your post setting nagra to windows 98 is a must if you go to the file you installed nagra from and right click ,it will give you the choice of running it in windows 98 compatability mode or just right click on nagra and go to compatability
now just gotta go through the couple of steps to get me back up and running
thanks so much mate!!!
