Okay...I suppose you have Win7 as OS? If not, then there could be your prob - mainly it's a driver and/or OS problem if the saber still isn't recognized. If it is Win7, then try to uninstall the launcher, re-install it (be sure you run the installer with admin rights - right click and "Run as administrator") and then start the launcher the same way you re-installed it. This should solve the issue. If not, then I have no other idea
