actually after downloading windows 8.1 the saber is recognize i can change the parameters of the motion etc
but i cannot change the sounds in my light saber it says device configurations failed
That's good news! The saber is recognized! This problem should disappear if you connect the saber to the launcher as before, EMPTY the right side colum of any files that are there, (dbl click on them to remove them), then add the sounds you like to an empty set of slots. Try that to see if everything goes through. (Forget just one default file that's there, and you'll get the error... it's easy to miss, but works bomb if you catch it).
