Both versions of the ActivExpressions take 3 x AA standard batteries that will need replacing over time, you should have got a “star” screwdriver with your set of ActivExpressions and it is a simple case of removing the single screw on the back and sliding the back panel off to reveal the batteries.
Once replaced with new ones you should be working again!
I have created a case on our system for you should you need to contact us further regarding this and the reference number for this is: 00493653
