here is your new save
Worked just fine for me, the ghost gave his speech and I could continue. I only noticed that I had to press Enter instead of clicking on the button.
You will be up for an upleasant surprise, though. I found the ghost level extremely hard. I read that with a cube it is ok, but you apparently used your second one already (as I did). It is possible using the saphire sword, but very frustrating.
