Try to completely remove the device from the Device Manager. Then connect the saber again, following these steps:
1) Charge the batteries to 100%.
2) Power the saber.
3) Connect the USB cord to the saber.
4) Connect the USB cord to the PC.
5) Check if Win 10 messages you that the saber has been set up.
6) Install the launcher with admin rights.
7) Launch the launcher with admin rights.
The saber should auto-connect now.
If it doesn't, note the step that gave you any issues and tell us. We'll try to get that solved - if possible.
I'm on Win 10 as well, and all of my sabers work fine...
ive done all of this and still gives me a yellow flag :/
