If I see a water mark on the lesson slides, how can I fix the problem?

The watermark will disappear from the slides between the course start date and course end date, as shown in iTeachVibration. 

To check these dates, Run iTeachVibration and click on the Dongle button.

Also check the ‘Date inside dongle’.  If this is different to the current date then please contact Training Support for help with re-initializing the dongle.
