Please make sure that you properly cleanup the previous setup first. To achieve this, after uninstalling the current setup through the Control Panel, under Programs > Uninstall a Program, reboot the computer and look through your Program Folders on c:\. If you find a folder named “EasyBits for Kids”, delete it. After that you may head over to our Download section and retrieve a fresh copy of the software. If your current key does not work anymore, please contact us, explaining the problem and providing your license key and a valid proof of purchase.
