What does the displayed message Error in initializing digitizer, when I start MovAlyzeR, imply?
This implies that either the digitizer driver is not installed on the computer or the driver needs updating. In order to use the digitizer tablet, the appropriate driver needs to be involved. (If you have a Wacom tablet, check http://www.wacom.com for the driver software). Please check your computer to see if the driver is installed and then retry opening the application.
