Hi Dunc., I'm a total technonumpty, and had a similar problem when I first tried to install 3.07, try this, with RB disconnected, start the RB program, then plug in the RB, you should get a prompt for automatic drivers - ignore that and opt for manual, open your C drive (or wherever you've installed the RB program) open the folder, until you see the driver file, double click on the file and (hopefully) it will install the RB driver. Sorry, if this is a bit unclear, I'm still trying to get 3.08 running, using the help and advice from the others....................
