Hi Jas,
Thanks for your comment.
Case 390629 has been raised, should you need to contact us directly.
Please can you let us know what the model number of the board is.
You can download the driver from here: https://promethean.box.com/ActivDriver-x64-v5-9-27
If the Pen still won't work, please remove the power supply and USB cable from the board for 1 minute and plug it back in. Calibrate the board and let us know what the result is.
Hope this helps,
Haymo
