You can try the following steps:
1. Press the Reset button on the side of the board. It's a very small blue button. (you may have to use a pen/pencil to reach it)
2. Unplug and replug the USB cable on the computer and restart.
3. If you have an extra USB cable, try switching it out.
4. You may also contact Smartboard Technical Support directly:
