Hi Natalie.
Thanks for posting on the forum.
You should have an ActivManager icon on your taskbar at the top of your screen, if you click on this and click on Control Panel, on the window that appears at the button will be a version number, please could you confirm this? Have you also tried to calibrate directly from the ActivManager>Calibration option?
Please could you also advise on the model number of your ActivBoard?
