When you start at Sunset Canyon, you ressurect Red S first, then when he tells you that he needs to ressurect his long time love...that is HELGA...so you bring her back to life. Don't do all 3 ghosts first because that will just screw the game up. I have done the same thing and had to start all over again.

all you have to do is ressurect helga, you can do all three ghosts ffirst(i found it
easier to get past that level)
