If you would like to post this enquiry via our web site (Topologika Educational software for children and adults at school, at home, in the UK or overseas) we'll be glad to help. Go to Product Support, choose Music Box 2, and complete the form. I'm pretty sure we've come across this one before and so we should be able to sort you out.
