DEVIL'S SHROUD - HELP PLEASE *****new*****

[sunshinegold]

Help me pleaseÃ,  :'(

I am either really stuck or really dumbÃ, 

I got the book of Satan from my bookshelf. I cannot do anything with it. When I try the computer it says that there is nothing there that looks like the blood on the 'door'.Ã,  I did not see any blood on the door (can't even look at the door) but I took a picture of the blood on the 'wall'.

I can magnify the blood from the wall but cannot open/use the book on Satan.

What am I missing.Ã,  I'm sure this is not a bug but an overlook from my part.

What else can I do

Thanks to anyone who can help me
