I wanna thank you all for your support, you have done alot to help me.
Nevertheless, Ed still doesn't say anything, nor does he give me the CD.

But I can speak to him when I'm not playing this adventure.
Perhaps there is something wrong on my computer so you guys have no problems in speaking to him.
I have already written an email to CN, and I hope they will sort it out for me.
If you have other ways to solve it, do tell me.
Thank you again for all your help.
