Application only worked the first time for each controller

[JimbertHimbert]

After using the program to change the colors of each my Joy-Cons, I closed it out and put them onto my Switch and saw that it had indeed worked. However, I wanted to make some tweaks to the colors and upon trying to open JC Toolkit again it simply will not open. I constantly get the "Connection Error!" screen, and no amount of disconnecting and reconnecting Bluetooth, or even restarting my computer does anything about this.

Hi @JimbertHimbert (assuming you have windows), go to the bluetooth settings and remove the joy con pairing from the list, the reconnect. Bit of a hassle to do each time but it works from me. Hope that helps
