Can you please try to turn off and on the board (or disconnect and reconnect) during the “Finding HW” scanning?
I know that this could sound silly, but it works most of the times.
We recently found a problem with the Main Launcher and it will be fixed on the next revision of the Sensor Toolbox software.
Please let me know if you still have problems after this.
If this don't solve your problem then you probably will have to re-program your board.
