Nero 7 breaking Musicmatch?

Ok, maybe someone here can help me. I have Nero installed, when I install Musicmatch Jukebox 10 I have to restart afterwards. Upon rebooting I get a message from NeroStart saying it fixed something and my CD/DVD drives may not work until I restart. After this Musicmatch works perfectly and my CD drives work too. However the next time I reboot Musicmatch doesnt recognize either of my DVD drives. Could this be because of whatever it is NeroStart is doing?

Tried it again, sorry it was NeroCheck that gives me the message at startup. Something about Upper and Lower registry.
