I purchased MUSIC MAGIX 29 online and it was working fine and I was able to use more that 8 tracks at a time but when I went to load a project that had more than 8 tracks on it ...it said that I had to buy them so I went to my PURCHASED PRODUCTS and it shows that I purchased it but there was no serial number under it and trying to get InTouch with TECH SUPPORT is very difficult...can anyone help out???
