Lost (HELP!!!)

Im am completely lost right now
Ok, so i just got Mixvibes w/ Maya 44 SE and i have no idea what to do. Yes, i have seen the videos on this website and the same one on youtube.
1. How do the inputs work? All of them are white so i dont know where to plug the RCA cables. (I am using one turntable, btw)
2. How do i update? I always get an error and "try again" always happens. I have version 7.1, but i cant update to 7.21
3. How do i download drivers? Same w/ the updates, i always get errors
4. My biggest problem is calibrating the turntable in the "install wizard". As i said im only using 1 turntable and im confused on steps 4,5,6 (Step 4&5, am i suppose to leave "no connected" on one of the connections because im using 1 turntable. Step 6 is calibrating it)
Im using Vista 64bit, also.
