At the end of Syberia 1, I pick up the mammoth automaton. Then Mr. Marson is supposed to call (according to all walkthroughs) and then the phone on the desk should ring (call from Helena). But none of this cutscene happens! Felix and Oscar act like Helena did call and I have to look for her, but she isn't there at the bar. So basically I am stuck and I never got to see the end of the first game.

Anyone who knows what to do?
