Puzzle. My X-Touch survived just fine through not only the March SONAR Platinum update, but also the most recent Windows 10 update.
I'm not certain that Cakewalk can fix the problem you are experiencing. It might be that the device is becoming unrecognized by Windows, so SONAR doesn't see the device and thus substitutes useless I/O devices for the control surface. Are you certain your Control Panel, Power Settings are set to keep USB devices from disconnecting to save power? A Windows update could have reset them.
