Hi ettrick, this is an often reported glitch, if running in demo mode as bc suggests, doesn't work, open up device manager and see if you've got the yellow patch beside the ANRB symbol under the USB devices, if you've got it click on it and use manual driver update to lead the RB to the driver file. When I initially installed my Win 7 64-bit, I had just the same problem, I found that if I loaded v. 2 and input my Home details, Long./Lat. etc., it would run OK, loading 3.13 it would then install and run fine.
