If you are trying to Continue the Demo from Version 1.0. You may need to start a new game because I changed the entire Demo, it's now on Version 2.0. Also, the Chapters that were on Demo 1.0 was 1, 7 and 12. On This new Version 2.0, the Chapters are 1,2,3 and 12. So, if you are trying to continue the Demo and if you were on Chapter 7, That chapter is no longer available on this demo.
