Making Back-ups

If the surface of a CD gets scratched it may not work in your computer. We are unable to replace, free of charge, disks that have been damaged. We therefore recommend that once you have purchased a disk from us, you make a copy of it onto your school computer. 

Alternatively, you may wish to purchase an aditional copy of each disk, to keep as a back-up. All disks may only be used in the institutions for which they have been purchased.
