Yes, GraphicAudio allows customers to authorize the wma downloads on up to 3 computers at a time. You can re-download the wma files from the website an unlimited number of times. You'll just have to make sure the wma files are located on your hard drive and open them using Windows Media Player. You will choose "Returning Customers" in the Media Rights Aquisition Window and enter your email and password to re-authorize the files. If you ever go over the 3 license limit, just contact us and we'll reset the license to zero.
