MPC Studio plugin issues

I have a mpc studio and I am having issues locating the sounds and plugin. I purchased from guitar center and it came with 3 disks, startup, the bank and 809 which stated were successfully installed because it will not let me reinstall them because it says they are already installed. But I cannot access anything. please help so I can finally take full advantage of the mpc studio experience. ps. am I missing any other disks besides the ones mentioned that I don't know about ? If so can you send them to me ?
