Hi. I HAD TO WIPE MY pc and reinstall my OS (Win 7 64 bit). How do i re-download my EZ Mix pack? I have 6 packs, and I am missing one. I right click on it and select reload, but this does not get me there. I am not sure what the serial # is for this, as I had 6 generic serials and matched them to the packs I selected. So, when I go to register/download I get a msg telling me that this is a generic serial. Any help is greatly appreciated.
