Hmm thats odd, but is there any kind of other burning software on your computer. If so it could be messing up Roxio software. Uninstall it if u do, and just keep roxio on there. Also go to roxio site, go to www.google.com and type in roxio homepage, look in there support ssection and see if there is any updates for the platinum edtition. And welcome to the guide.
